Psycher

Nobody  really  knows how Psychers work, considering that their very presence causes nightmares in every human that they're around. What's known is that they're some degree of mutant, but nobody exactly knows how they developed psychic abilities. In truth, they're actually people that have come into contact with alien technology from the meteorite. They can also teleport (and teleport others through the use of portals, which resemble swirling purple vortexes.

Altos primarily operate on a hive mind. They frequently and rapidly mutate (such to the degree that people have watched them grow more muscular while actively being looked at), but primarily they resemble incredibly lanky, shiny black skinned humanoids, and as a rule, has pitch black skin, and bright purple eyes. No other facial features can be seen generally, although in captivity, Psychers occasionally "grow" a mouth in order to eat food, only to have to seal itself shut when no longer required.

It's believed that they have a queen, that through the use of a hivemind, instructs them to gather both biomass and material, primarily to make more Psychers, and construct their "hives" (which resemble large organic spires). Occasionally, a drone will become disconnected from the hive - if they're in the hive when this happens, they'll be immediately mulched down for biomass, but if they're out and about, they can occasionally get picked up by humans and used as teleporters. Once disconnected from the hivemind, echoes of memories from their human lives slowly return to them.
