I went looking for Annah in the Hive so I could improve Morte's Litany of Curses. She's not in her spot in the northeast Hive pillar, and I'm sure I didn't kill her. I know she's been there before, as I've heard her voice when fighting some thugs in the area. Has anyone else encountered this?

Maybe she disappears from the Hive when the player meets with Pharod? Have you found him yet?

Solar, just keep playing the main plot and you'll find her again ;) This is supposed to happen if, as Wyndfyre stated, you've found Pharod.

No, haven't found Pharod yet. I'll continue on and see what happens.
