Hello, I was just wondering cause I am finishing The Thieves Guild. I am right now at Aren's Lab I am suppose to find some keys in right rear corner but there is no keys...I went all the way out the dungeon and I find anther door but I can open it. Am I missing something?

I don't know if this is a spoiler, but you know that little bit of water in that cave with Slaughterfish? Dive into it, and you'll fine a cave with a bit of searching - that's where you go the next area. Might want some method of water breathing to find it though.

Unfortunately this question cannot be answered in the Oblivion General forum, it has to be moved to Oblivion Spoilers forum. I'll see if I can get a moderator to move it.

Edit: Okay, it has been moved now.

The same chest where you find the Arrow of Extrication (to the right, in front of Fathis Aren) should also contain a key called something like "Fathis Aren's Tower key." If it doesn't, Fathis Aren should have one on his person of the same name. You could try pick pocketing it off him while he's mixing his potions in the dungeon.

Oooooops oh ok....thanks....sorry for posting it in the wrong place.

Ok, I'll try this and let you know later...and thank you for the tips!!!!

ok this quest is a little confusing but I finally complete the quest, thanks for the comments it helped allot. Cause I think people keep looking for in the dungeon but actually he is outside in the tower and where he is mixing his poisons that is where the chest is. Thank you!!!
