For my money it's tough to exceed the tongue-in-cheek commentary you'll find in the books scattered around Acherus as you start a career as a Death Knight, including the one pictured above. Some of them are actually serious and give accounts of the Scourge's spying into the preparations made by the Horde and the Alliance for an assault on Northrend. Some of them, like The Death Knights of Acherus, are just hilarious, namely the entry concerning one "Harmony" whose period of service turned out to be extremely brief: "The name of this death knight was found in violation of common Scourge decency. Struck down by the Lich King." Well, Arthas, in such matters I defer to your excellent judgment.
