Okay, I've gotten to the ceremony where the Matron Mother summons the demon, and I've interrupted the summoning like my quest log says to. But I can't find the eggs, and whenever I go back to the dragon, she tells me I've failed the mission. What am I missing? I've tried picking pockets, and their magic resistance prevents pretty much everything else.

BEFORE going to the temple, talk to the M.M.s daughter. She will give u some fake eggs and give you a key so as to steal the original ones. Now, I suppose you HAVENT killed the drow fighter for her, because if you did I cant help you. But if you let him live, he will give you some more fake eggs...
