The Stars are Fire
Vacuum fungus is sometimes found as a greenish ooze on the exterior of spacecraft or space stations, growing in fine lines through the ice of frozen moons, and infesting the center of small asteroids and near-Earth objects (NEOs). Though able to survive in vacuum, the fungus takes on new morphology when sufficient spores find their way into habitable zero-G spaces. Then they fuse together and grow into a bulbous, emerald-hued fruiting body, typically reaching about 1 m (3 feet) in rough diameter, though individuals can grow much larger if not discovered. Sticky and soft to the touch, they are able to grow undetected in the dark corners of cargo holds, in ductworks, hanging from the ceiling of unused crew quarters, and so on.
Vacuum fungus may be proof that extra-terrestrial life exists, but that triumph of scientific discovery may seem less important to those who find a clump, because they are incredibly toxic to living creatures.
Motive: Reproduction
Environment: Anywhere in zero G, as an unreactive ooze in vacuum, or as a fruiting body in atmosphere, alone or in a cluster of three to five (Space)
Health: 22
Damage: 6 points
Movement: Climbs (adheres) an immediate distance each round
Combat: A fruiting body can selectively detonate spore pods along its surface once per round. When a pod detonates, green fluid sprays everywhere within immediate range. Living creatures who fail a Speed defense roll take 6 points of damage from the clinging fluid. An affected target must also succeed on a Might defense roll. On a failure, an affected section of flesh rapidly swells, becoming a bilious green lump, and explodes one round later, having the same effect as a detonating pod.
Interactions: No real interaction with vacuum fungus is possible.
Uses: Scientists are incredibly excited to discover that the strange ooze they've noticed staining the exterior of their research domes is actually a variety of fungal life. They will likely become less excited when they discover the large growths secretly growing in the cavity beneath the floor of their research dome in a little-used storage closet.
GM Intrusion: Striking the vacuum fungus clump causes one of the spore pods to detonate immediately, even though it's out of turn.
