OK ive beat up little jon and yoshimo ran into that one guy and he offerd me a deal and i took him up on it. but when i saw him in the tavern and explained that he had no ship and that he wanted my help in getting a new so i told him to stuff it and that im going through the portal. now that portal is on the other side of this door and i cant open it!!!!!!! you cant pick it and no spells will work how the heck do i open this door???
if anybody can help please do thanks a bunch

If you're certain about using the portal, the key is on the first level of the asylum, in the little bedroom place. Personally I wouldn't bypass the Sahauguin part for the world, since it means missing out on the Cloak of Mirroring.

ok how do you know all of this? I take it that you have been through this game many many times.

Close to finishing it for the second time...
