Unkillable EQ Monster Killed

How long does it take almost 200 high-level EverQuest players to vanquish a monster that was given a hundred billion hitpoints to discourage anyone from trying to kill it? They found out recently on the Rallos Zek server, when several top guilds set out to do what allegedly couldn't be done. An excellent post on Got Game gets into the motivation for the event. "For those non EQers out there a reference scale: a snake has about 10 hitpoints. A dragon has about 100,000. A god has 1-2 million. This sleeper thing (Kerafyrm) really does have about a hundred billion or more." One of the guilds involved got a screenshot, which will hopefully make up for the lack of loot. (Thanks Slashdot.)
