Reading the new official preview of the Ruby Sanctum made me think about how Blizzard can transition from that into Cataclysm. I know she's come up before, but I keep thinking of Nalice, the Black flight emissary at Wyrmrest. She makes fairly overt intimidating statements to player characters despite their cooperation, and the mere fact that the Ruby Sanctum is infiltrated covertly just screams that she had to be involved in opening the door for Halion's assault. I would love for a pre-expansion quest line or in-game NPC event to end with her MWUHAHAing about the coming danger, morphing into dragon form, and flying off of Wyrmrest. I'd love to see her reused in Cataclysm as either a raid boss for a 1st tier raid (if there's one about black dragons) or as a boss encounter in a later instance.
