World of Warcraft: The Burning Crusade Dungeon Details

Blizzard's official World of Warcraft website has been updated with new pages dedicated to "almost every raid and five-person dungeon" in The Burning Crusade expansion pack. A snip about Karazhan:
Medivh, the Last Guardian, made his home in Deadwind, in the bright tower of Karazhan. Though he was the greatest wizard of his day (and humanity's intended custodian) Medivh was secretly possessed by the dark spirit of Sargeras, the Destroyer of Worlds. Through Medivh, Sargeras opened the Dark Portal and allowed the orcs to wage war upon the mortal kingdoms of Azeroth.
