Well, I have a new one fellas: Created them.
Or rather, just Ateris. My character, Ateris is a special case, since it lives its life in physical pain (its inner body structure is so messed up, it doesn't function like any creature we know of on Earth.)
Ateris used to be an arena fighter for an alien race in its past life. I was debating making it human at one point, but then I decided I could fit that in in some other way. Ateris had an appearance that looks somewhat similar to its current one, although this past appearance looks a lot healthier and more.. whole..? Not really sure how to word it. Anywho, Ateris was a champion at this sort of fighting until one day, a fighter who was some sort of demonic space entity arrived and knocked Ateris out of the ring. The aliens left Ateris, now supporting this new entity, and Ateris was supposed to die here.
It did not.
Ateris, bleeding and tired, dragged itself to a cave where it went to sleep, and healed surprisingly fast (which was influenced by another entity.) Eventually, the entity contacted Ateris through its mind and told Ateris to "kill them," and Ateris was pretty much like Why would I do that? at first, but the entity told Ateris it had healed Ateris, and promised more power if Ateris followed its desires. Ateris, recalling how it was brutally kicked from its spot and left to die, went to kill the space entity, and succeeded, but the other influencing entity left it, hoping to return once Ateris was killed by the aliens and use Ateris' body as a shell. However, Ateris didn't like this and let's just say the aliens didn't have a good day that day. A leader of the alien race saw this and cursed Ateris to another planet where it would live its life in 'eternal pain' without being able to die. A cost of the curse was wiping the memory of Ateris, though this was good, should Ateris ever achieve space travel, it would not return to their species. That planet was earth. Ateris lived there for a long time, and like I said, living life in pain, but also causing pain to living creatures around it. It survived some extinction events but fell asleep, then woke up, and boom, there were little villages everywhere.
The rest is history. Literally. And future, as well.
