I sold the three archangel statues to that Arab dude not knowing I would need them to get into St. whats-his-name's tomb. Now the Arab guy disappeared so I can't get them back. Will I ever be able to get into the tomb now?!?!

I think that everything should be all right, Ihman ab Sahab only moved to the entrance to the St. Orthenius's tomb because he wants to get inside as well.
