er... Have you tried talking to the paladin again? I believe he gives you some experience and then you are teleported back.
He won't talk to me. I click on him and nothing happens. He is just a Paladin, not a Sir, according to the balloon over his head. There are no black areas on the map.
Someone here mentioned treasures. There are one or two chests I can't open. Other than those I didn't find any great treasure here.
