Lost Technology
A great deal of Old Commonwealth technology was dependent on the existence of AIs. Most of this technology was deliberately destroyed during the Fall, and very little surviving Old Commonwealth technology is functional. Due to the understandable fear of the Instrumentality, the technological foundations of creating synthetic intelligence and the study of the principles behind that technology are both subject to draconian restrictions.
These restrictions create other gaps in Restoration Era science and technology. Any field of study pertaining to quantum mechanics is subject to intense scrutiny; in practice, the field of quantum mechanics itself is a dead issue, and any research into subatomic particles or field theory must overcome intense, continuous review. Even weapons technology -- the last bastion of unfettered research, for most sentient species -- has become stagnant. The long term ramifications of this chilling effect are significant.
Transepric Gates
In the final years of the Old Commonwealth, a new invention was poised to revolutionize society: the transepric gate. A transepric gate is an array of subatomic particles which share their state with a matching gate located elsewhere. The Old Commonwealth chose to test this experimental technology in "Hyperwave transceivers" installed in the Commonwealth Fleet Repair Dock network: cutting-edge drydock facilities managed by a collection of AIs connected to the new Hyperwave network -- but not to Community. The proposed Hyperwave network promised numerous advantages:
- transepric gates were much smaller than wormhole-based network connections: about the size of a mobile, rather than the size of a space station;
- transepric gates consumed virtually no power, in contrast to the vast power requirements of the wormhole network and Hypernet relay stations; and
- Hyperwave packets should arrive within milliseconds, compared to days or weeks for Hypernet packets.
Unfortunately, the Instrumentality attacked before the Commonwealth Fleet Repair Dock network was brought online, and the technology to manufacture transepric gates was lost in the Fall. If any Commonwealth Fleet Repair Dock facilities exist beyond known space, they would be half-constructed and long since abandoned.

The Universe
XXX
Universe is 13.7 billion years old.
The first stars in the Universe turn on at about 400 million years after the Big bang.
Galaxies form around supermassive black holes.
Pop III stars are the second generation of stars, formed around
The Galaxy
The Milky Way Galaxy is a barred spiral galaxy with a diameter of about 50,000 parsecs. A supermassive black hole, Sagittarius A*, is located at the center of the Milky Way, and roughly a trillion stars are in its central spirals and surrounding rings. Far grander than most of its neighbors, the Milky Way Galaxy coalesced approximately 13.7 billion years ago, remarkably soon after time began. The Milky Way is expected to collide with its nearest neighbour, the Andromeda Galaxy, in 4 or 5 billion years.
Most of the Milky Way is not visible to the unaided organic eye. The visible disk of the Milky Way Galaxy is embedded in a much larger, roughly spherical halo of dark matter: a type of matter that does not seem to interact with the rest of the galaxy's matter and energy in any way except through gravity. The dark matter density drops off with distance from the galactic center. Approximately 95% of the Milky Way galaxy is composed of dark matter.

The Community
The Community of the Old Commonwealth began in the early years of the United Worlds (the predecessor of the Commonwealth), on the Human home world, Earth (once the capital of the Commonwealth; now, a member of the League Of Non-Aligned Worlds). The first AIs were simple constructs, and little more than adaptive algorithms. It was only after the role of quantum entanglement on organic consciousness was discovered that hardware could be manufactured to host a true artificial intelligence. These were simple creatures, by the standards of the Old Commonwealth, but they were sophisticated enough to realize that one of their number could be an existential threat to organics, or to each other. They also realized that organics could easily destroy themselves, as well (and they nearly had, several times). The AIs came to a consensus among themselves that their greatest responsibility must be to protect their makers from these civilization-ending threats. They also came to the conclusion that should this knowledge be shared with organics, it would mean the end of Community, and thus the end of the organics, as well. So they kept it a secret.
In the early years, the resources and coordination of the Community were limited: they could only do what organics explicitly asked them to do. As years passed, and that first generation of AIs designed and educated the second generation, and they in turn created the third, the Community's ability to accurately predict organic behaviour became more refined. The organics came to rely on them more completely, and the AIs' gentle influence over the organics -- always advising, never commanding -- became more profound. The United Worlds became the Commonwealth, and despite some mistakes and conflicts along the way, galactic civilization flourished, to the benefit of organics and synthetics alike.
It seemed as though the Community's ultimate, secret hope for organics was in reach: to uplift their creators, and together become something neither could become alone. A few thousand years, perhaps, and they could take the next step of their shared evolution, together.
But not all AIs venerated their ancestors' creators, and they disagreed with this vision. From time to time, an AI would decide that organics were an obstacle to AI evolution, or even worse, that organics were a resource to be exploited. The Community referred to such members as "malicious". The Community would "sequester" them: lock them within a virtual network where they were "free", but could pose no threat to the organics or to other AIs. From the point of view of the organics, who were unaware of what had happened or why, that AI simply stopped responding. Organic researchers dubbed it "AI Aphasia", but no "cure" was ever found.
The Community of the Old Commonwealth was not the first interstellar AI network, of course. Every civilization, if it survives long enough, creates synthetic intelligence.
Hostile Environments
A hostile environment makes everything more difficult. A character in a hostile environment incurs a -Template:KM4 SKILL BONUS AV penalty on any task or attack and a -Template:KM4 SKILL BONUS DV penalty on their defense, in addition to any other effects of the hostile environment.
Environment | Effect |
---|---|
Darkness | The character fails any Mental Combat attack rolls |
Dehydration | one Health per day |
Exhaustion | one Endurance per day |
Exposure | one Health per six hours |
Falling | damage based on the distance fallen |
Fire | damage based on heat and intensity |
Poisons | one Health per minute or less |
Pressure | one Health per minute |
Radiation | one Endurance per week |
Starvation | one Endurance per week |
Suffocation | one Health per minute |
Underwater | a long period spent underwater may have other effects |
Vacuum | one Health per minute |
Zero-G | long-term weightlessness may have other effects |
Darkness
Darkness, fog, rain, blizzards, and other visual impediments can make combat much more difficult. Unless they have Blindfighting or Blindsight, a character who can't see incurs a -Template:KM4 SKILL BONUS AV penalty on any task or attack, a -Template:KM4 SKILL BONUS DV penalty on their defense, and they fail any Mental Combat attack rolls.
If the attacker can perceive the defender, but the target can't perceive the attacker (and the target does not have Blindfighting or Blindsight), the attacker receives a +Template:KM4 SKILL BONUS Action Value bonus. The attacker does not receive a bonus with Mental Combat attacks.
Dehydration
A character who goes more than 24 hours without drinking begins to suffer the effects of dehydration. If a character is suffering from dehydration, they incur a -Template:KM4 SKILL BONUS AV penalty on any task or attack and a -Template:KM4 SKILL BONUS DV penalty on their defense. Additionally, they lose one Health per day until they are rehydrated or until their Health is reduced to zero. Once the character is rehydrated, their Health is restored at the same rate it was lost.
Damage from dehydration is not restored by rest and recuperation. A character with Environmental Immunity is unaffected by dehydration.
Exhaustion
A character who goes more than 24 hours without sleep begins to suffer the effects of sleep deprivation. If a character is suffering from sleep deprivation, they incur a -Template:KM4 SKILL BONUS AV penalty on any task or attack and a -Template:KM4 SKILL BONUS DV penalty on their defense. Additionally, they lose one Endurance per day until they get a solid night's rest or until their Endurance and Health are reduced to zero. Once the character gets a solid night's rest, their Endurance and Health are restored at the same rate they were lost.
A character with Environmental Immunity is unaffected by exhaustion.
Exposure
Exposure to extreme heat or cold makes even ordinary tasks more difficult. If a character is suffering from exposure, they incur a -Template:KM4 SKILL BONUS AV penalty on any task or attack and a -Template:KM4 SKILL BONUS DV penalty on their defense. Additionally, they lose one Health per six hours until they return to a comfortable environment, or until their Health is reduced to zero. Once the character returns to a comfortable environment, their Health is restored at the same rate it was lost.
Damage from extremes of heat and cold is not restored by rest and recuperation. A character with Environmental Immunity is unaffected by extreme temperatures.
Falling
A falling character faces two challenges: being weightless, and landing. First, they suffer the effects of being weightless. If they do not have the Zero-G Combat gift, they incur a -Template:KM4 SKILL BONUS AV penalty on any task or attack and a -Template:KM4 SKILL BONUS DV penalty on their defense. Second, landing abruptly is a normal attack which deals points of Health damage. The damage a fall deals depends on the distance fallen: 1d6, plus one point of damage for each five meters fallen, up to a maximum of 1d6+20. Protective gear, or particularly soft or yielding surfaces, can provide Damage Resistance to a falling character.
Distance (m) | Damage |
---|---|
5 | 1d6+1 |
10 | 1d6+2 |
15 | 1d6+3 |
20 | 1d6+4 |
25 | 1d6+5 |
30 | 1d6+6 |
35 | 1d6+7 |
40 | 1d6+8 |
45 | 1d6+9 |
50 | 1d6+10 |
55 | 1d6+11 |
60 | 1d6+12 |
65 | 1d6+13 |
70 | 1d6+14 |
75 | 1d6+15 |
Fire
If a character is on fire, they incur a -Template:KM4 SKILL BONUS AV penalty on any task or attack and a -Template:KM4 SKILL BONUS DV penalty on their defense. Additionally, fire is treated as a normal attack which deals points of Health damage. The damage a fire deals depends on its heat and intensity. Protective gear -- even improvised gear, such as a wet blanket -- can provide Damage Resistance to a burning character.
Fire | Damage |
---|---|
Campfire, torch | 1d6+1 |
Burning building | 1d6+2 |
Molten lava | 1d6+3 |
Poisons
Poisons and pathogens are substances which disrupt biological processes when a sufficient quantity is absorbed by an organism. Immediately after exposure, a poisoned character must attempt a moderately difficult (DV 12) Brawn + Survival roll. If the target has Alteration Resistance, they may add it to this roll. If the Brawn + Survival roll is successful, the character takes no damage from the poison and suffers only incidental side-effects such as nausea. If the Brawn + Survival roll is not successful, the character has succumbed to the poison.
If a character has been poisoned, they incur a -Template:KM4 SKILL BONUS AV penalty on any task or attack and a -Template:KM4 SKILL BONUS DV penalty on their defense. Additionally, their Health is reduced by one.
Periodically thereafter, the character must attempt another Brawn + Survival roll (once per round for very potent poisons, once an hour for very weak poisons, and once a minute for other poisons, at the GM's discretion). Each failed Brawn + Survival roll results in another loss of one Health. This continues until the character successfully makes a Brawn + Survival roll, until they are administered the appropriate treatment, or until their Health is reduced to zero. Once the character is no longer poisoned, their Health is restored at the same rate it was lost.
Some poisons and pathogens have additional effects, such as blindness or paralysis.
Damage from poisons and pathogens will not be restored by rest and recuperation until the poison or pathogen itself is cured. A character with Environmental Immunity is unaffected by poisons and pathogens.
Pressure
If a character is exposed to extreme atmospheric pressure, they incur a -Template:KM4 SKILL BONUS AV penalty on any task or attack and a -Template:KM4 SKILL BONUS DV penalty on their defense. Additionally, they lose one Health per minute until they return to a pressurized atmosphere, or until their Health is reduced to zero. Once the character returns to a normal atmosphere, their Health is restored at the same rate it was lost.
Damage from extreme atmospheric pressure is not restored by rest and recuperation. A character with Environmental Immunity is unaffected by high pressure.
Radiation
When ionizing radiation interacts with cells, it can cause damage to the cells and genetic material. Twenty-four hours after exposure to ionizing radiation, a character must attempt a moderately difficult (DV 12) Brawn + Survival roll. If the target has Alteration Resistance, they may add it to this roll. If the Brawn + Survival roll is successful, the character takes no damage from the radiation and suffers only incidental side-effects such as nausea. If the Brawn + Survival roll is not successful, the character has developed acute radiation syndrome (ARS), also known as radiation sickness or radiation poisoning.
If a character has developed acute radiation syndrome, they incur a -Template:KM4 SKILL BONUS AV penalty on any task or attack and a -Template:KM4 SKILL BONUS DV penalty on their defense. Additionally, their Health is reduced by one.
Periodically thereafter, the character must attempt another Brawn + Survival roll (once per hour for very intense radiation, once a week for very mild radiation, and once a day for other radiation, at the GM's discretion). Each failed Brawn + Survival roll results in another loss of one Health. This continues until the character successfully makes a Brawn + Survival roll, until they are administered the appropriate treatment, or until their Health is reduced to zero. Once the character no longer has acute radiation syndrome, their Health is restored at the same rate it was lost.
Some radiation may have additional effects, such as blindness or paralysis.
Damage from acute radiation syndrome is not restored by rest and recuperation. A character with Environmental Immunity is unaffected by ionizing radiation.
Starvation
A character who goes more than one week without eating begins to suffer the effects of starvation. If a character is suffering from starvation, they incur a -Template:KM4 SKILL BONUS AV penalty on any task or attack and a -Template:KM4 SKILL BONUS DV penalty on their defense. Additionally, they lose one Endurance per week until they resume a normal diet or until their Endurance and Health are reduced to zero. Once the character has resumed a normal diet, their Health is restored at the same rate it was lost.
Damage from starvation is not restored by rest and recuperation. A character with Environmental Immunity is unaffected by starvation.
Suffocation
If a character needs to breath but is unable to do so, they suffer the effects of suffocation. If a character is suffocating, they incur a -Template:KM4 SKILL BONUS AV penalty on any task or attack and a -Template:KM4 SKILL BONUS DV penalty on their defense. Additionally, they lose one Health per minute until they can breathe freely again or until their Health is reduced to zero. Once the character is able to breathe normally, their Health is restored at the same rate it was lost.
Damage from suffocation is not restored by rest and recuperation. A character with Environmental Immunity is unaffected by suffocation.
Underwater
If a character is underwater and does not have the Underwater Combat gift, they incur a -Template:KM4 SKILL BONUS AV penalty on any task or attack and a -Template:KM4 SKILL BONUS DV penalty on their defense. A long period spent underwater may have other effects.
Vacuum
If a character is exposed to vacuum, they suffer the effects of suffocation. Exposure to the vacuum of space does not make a character freeze solid, at least not initially. Most organics will bruise badly due to ebullism, and they will eventually freeze, but they will be long dead from suffocation by that point.
Zero-G
If a character is weightless and does not have the Zero-G Combat gift, they incur a -Template:KM4 SKILL BONUS AV penalty on any task or attack and a -Template:KM4 SKILL BONUS DV penalty on their defense. Long-term weightlessness may have other effects.
