Ok I know this is most probably a silly question but where do I get a Castle Leyawiin Key? I am trying to do Adharji's Heirloom quest and every time I pick the lock on the bedroom door it wakes up the count which then wakes up the countess.

I am guessing that I have to pickpocket to get one. Who is the best person to do that with?

Thanks in advance for any help or advice!

Pickpocket any Leyawiin guard you see. They will have the key on them.

EDIT: Another way would be to pickpocket the other staff in the castle.

I found it easy to stand behind the thrones during the day and steal it from the countess herself (along with the other things she has )

Thanks for the help all.....it took me a while but I finally managed to finish this quest.

I don't think you can pickpocket an item that the NPC is wearing.
