Thanks to Got Game? for their posting discussing the in-game slaying of Kerafyrm, aka The Sleeper, in PC MMO EverQuest. This event, commemorated with a screenshot on the site of one of the guilds involved, is notable because the players "...killed what Sony Online Entertainment intended to be unkillable. But rather than actually make it untargetable, Sony just gave it a hundred billion hitpoints. For those non EQers out there a reference scale: a snake has about 10 hitpoints. A dragon has about 100,000. A god has 1-2million." So, it took "close to 200 players almost 4 hours to beat the thing down into the ground", after an earlier failed attempt where the guilds "beat it down to 27% and then it mysteriously disappeared. Without dying. It seems that one of the Game Masters at SoE reset the zone because 'they thought the encounter might be bugged'."
