The sundered capstone was a bad sign, but he still had a small hope that the opening of the door had gone unnoticed by the ancient spirit. Perhaps it had not yet reclaimed the portion of its power that lay entombed here, giving him a chance to block the opening until he could gather others to seal it again. If he probed the well and the spirit was awake and aware, it would try to take him. He feared that he was not strong enough to deal with it by himself, but no one else was here. If he took the time to summon others, the chance would likely be lost.
