Kerafyrm (also called "The Sleeper") is a boss character in the fantasy MMORPG EverQuest. Originally intended to be unkillable, the character caused a stir in the EverQuest community when the developers of the game (Sony Online Entertainment (SOE) intervened and prevented a group of nearly 200 players from killing him, in November of 2003. SOE later apologized for interfering, and allowed the same group of players to retry the encounter. After a nearly three-hour battle, Kerafyrm was defeated.
