Dying in Space
Floating unprotected in the depths of space is bad news for anyone but an Urdine. Even mechanical beings such as Sisters can be damaged by cosmic rays, struck by minuscule meteors traveling at near light speed, or broiled one moment and frozen the next. Still, fleshy beings have it worse, as their bodily fluids boil and their flesh shreds itself.
An unprotected human, thrameexis, duurl or utir in deep space must make a Survival check and a Resilience check every turn. (A turn is 3 seconds.) Both tests start at a threshold of 40 and increase by 5 for each successive round. Failure on either test results in unconsciousness and then, one turn later, death. Accident reports and experiments show that most can survive in space for around 10 seconds, many can reach 30 seconds and the “hard limit” for humans is around 1 minute.
Proper equipment makes space walks safe and even exciting, but a cosmonaut adrift in an EVA suit has only delayed his horrible death. In this case survival depends on how much breathable air is available for the lost soul to breathe, and how well the cosmonaut stays calm and rations the air. Determine the capacity of any air tanks and then make escalating Survival tests (40, +5) every 10 minutes or so. Failure decreases the tank capacity faster than normal at GM discretion.
