Sleeper

In online role playing games, a sleeper is a character created by a player that is soon abandoned by its player. The character technically lives on in the game world but never speaks, works or interacts with other characters because its player no longer plays him/her. As a result, the character is often deemed a "sleeper" by the active characters and ignored until he/she succumbs to starvation or some other form of character death in the game or less commonly the player has a change of heart and decides to start playing the character again.

This is how it usually goes.

A character named Argon is born or spawned into the game world.

Argon: "Hello everybody what can I do to help out around here?"

Random character: " Argon, we could use a guard to help defend the city, maybe a blacksmith."
Argon: "Okay, sure."

One or two weeks later.......

Random Character: That Argon fellow hasn't spoken in two weeks. He made a hammer and then fell a sleep. He's a sleeper sojust let him starve."

Sleepers

Not just sleep. It's the most comfortable and cozy nap ever. Just curl up in a little ball and shut out the world.

I'm so glad to be back home in my own bed, I'm going sleepers.
