I am currently stuck on this quest, ive searched the rooms up above the chest that lies underneath the stairs (its my understanding its in that chest where the quest item lies), I have found 2 keys which have opened up the chests upstairs but the one downstairs for this quest remains locked, ive continued to check all the rooms for any additional keys but so far to no avail, please assist in any way possible to advise of where the missing key is, thank you.
