Congratulations, you just found the "I go to the Pirate lord, talk to him and dont get commited to the asylum, then I use the stone from the adept to get in and nothing happens when I get inside" bug.
None, reload and make sure that either get the pirare lord to commite you or go the the adept, kill him and use the stone, never take both paths (go either by the pirate lord or the stone, never talk to the pirate lord if you wish to enter by the stone or dont go to the adept house if you want to use the pirate lord to get in).
