Unfortunately I can't find her in the castle. I've taken the mage's path but she's not in the teleport room. Nor is she anywhere in the castle. And I pretty much looked everywhere. I don't think I've missed anything. It might be a game breaking bug.
yes i've had same thing happen to me, i took the path with the cook though, there was a quest marker while i was with the cook for like 2 of his sub-quests, but it went away and when i got in the castle there was no one after searching it at least 4 times, must be some sort of bug cause i have no quest mark and no one in the teleport room
