Ender

Ender is a creature made of dark matter, based on the enemies known as Endermen in Minecraft.

Ender was spawned in The End, but eventually escaped to Cloud City to live free from responsibility as an enemy. She got a job at the local power plant and worked there until she eventually met Ox on a skydiving trip. Ox and Ender have lived together since, going on adventures in doing whatever is relevant at the moment.

Sometime in her life, she was stabbed repeatedly in the voice box making it impossible for her to speak. Using a bit of dark magic and Blacky's power though, she made a new voice box for herself modeled after Ox's voice.
