"Wrathgate" is the second in-game cinematic from World of Warcraft: Wrath of the Lich King, and it's quite a big spoiler for the upcoming expansion - so consider yourself warned before watching the trailer or reading any further! In it, Apothecary Putress and Varimathras betray Sylvanas by killing Horde, Alliance and Scourge alike. Saurfang gets killed by Arthas the Lich King, Bolvar dies to the plague unleashed by Putress, and the Red Dragonflight pours down the flames on the corpses to spare them the curse of rising as undead.
