And just in case you didn't know(I didn't until they killed it) the Sleeper is the ultimate GM screwup; on EQ, it was a creature that was supposed to be unkillable. Last week, it got killed. The mistake? Giving it HP(granted, 100 billion HP, but still) as opposed to just making it unkillable.
Anybody remember hunting the Norse Gods in high school using Deities and Demigods in 2nd edition?
