Endermen

Endermen are tall, creepy, purple-eyed men who live in the land of Nowhere. They like to walk around aimlessly, as all things in Nowhere do, and they sometimes pick up bits of ground and move it somewhere else for no apparent reason.

If someone looks them in the eye, however, they will teleport quickly towards them using their Ender Pearls and attack. They can be avoided easily, because they don't like water or fire very much. They like to work alone but can sometimes be found in little groups, trading random pieces of dirt for.... more random pieces of dirt.

They are also apparently members of Herobrine's Legion of Death, but if they are, they aren't much help.
