Alien Species

See the official Eternal Cylinder wiki as this information is outdated.

The Eternal Cylinder is a gigantic, megastructure-like being, and the master to all its Servants. It arrived onto the Trebhum planet billions of years ago along with its servants, with means to destroy the entire planet by steamrolling it all. No one knows where it came from or how it appeared by modern times.


As the name implies, its body is in the shape of a cylinder. It doesn't possess any organic materials anywhere on its body. The exact size of it is beyond comprehension, as it seems to be so long it could destroy an entire ecosystem in a matter of minutes.


  • Electricity - When enraged, it is able to generate bolts of lightning to attack lifeforms across the land, though it is unknown how it is able to do this. It can't shock beings closer to it however, as it appears to be strictly a long-ranged attack.
  • Molten body - When in motion, it heats up its entire mass to the point of being compared to molten lava, making it easier to crush and destroy constructs, animals, and environments in its way. This ability is stopped though if it ends up blocked by something, or if any other method makes it stop.
