Anomalies: Oxygen atmosphere is produced by photosynthesis of Centiworms, Extra solar xenos life form – Centiworm

The moon in question orbits a gas giant in a far-off corner of the galaxy. Its atmosphere is rich in methane and ammonia, but has very low oxygen content, making it impossible for humans to breathe without protective gear. The surface of the moon is barren and rocky, with jagged cliffs and deep crevasses crisscrossing its surface.

Despite its harsh environment, the moon is teeming with life. However, the dominant life-forms on this moon are not what one would expect. Instead of plants and animals, the moon is inhabited by a species of centipede-like creatures that are extremely dangerous.

These creatures are covered in hard, chitinous plates and can grow up to several meters in length. They have dozens of legs, each ending in sharp claws that can rend through solid rock. Their heads are dominated by large mandibles, which they use to crush and devour their prey.

These centipede-like creatures are the apex predators on this moon, and are feared by all other life-forms that inhabit it. They hunt in packs, using their superior speed and strength to take down even the largest of prey. Their senses are finely attuned to the moon’s low-oxygen atmosphere, allowing them to navigate easily in even the most treacherous terrain.

Despite their fearsome appearance, the centipede-like creatures are not unintelligent. They communicate with each other through a series of clicks and chirps, and have even been known to work together to achieve a common goal.

For humans brave enough to explore this moon, the centipede-like creatures are a constant threat. Any misstep could mean a swift and painful death. But for those willing to take the risk, the moon holds the promise of discovery and adventure, as well as the chance to study one of the most unique and dangerous species in the galaxy.

Centiworm

Parasitical insect evolved in some unknown warp traveling vessel’s bilge. Invaded Irae  from passing which dumped it’s bilge on orbit of Impensus and became endemic species at the moon. Backround radiation is food source of Centiworm. Irae surface they are not able to grow bigger than huge. I fCentiworm finds good source to feed it may grow to gargantuan size.

Size: Small to Huge
Traits:
Sense heat
Poisonous, invulnerable to fire, vacuum, electricity, radiation, acid
Small: Can burrow through skin and invade internally.
Huge: Ferociosly hungry as solar radiation feeds it barely.

Story thread: Prison warden Vladir pays handsomely for alive specimens of centiworms. Bigger the centiworm, bigger the profit. His bounty bring steady amount of mercenaries capturing centiworms at Irae.
