It seems we stumbled onto something we were not prepared for. We finished off the rogue but it turns out he was nothing but a traitor to begin with. An Abishai sworn to Tiamat in service to her to find passage into the Giant' tomb. The giant was stymied by Tiamat in the ancient past and we were able to answer the riddle that insured his downfall. As a reward Nimbus was given a warhammer of surpassing power to assist in quelling the spirits of whatever is down in that tomb. Unfortunately we will not know as we barely were able to retreat with out lives after we foolishly pressed on after out hard won fight with the Abishai.
