After fruitlessly searching the wall behind the bookcase, Therren turns his head somewhatly wildly, eyes frantically glancing around the room for inspiration. Looking again at the three central figures in the mozaic, he walks back to the them so that he can more closely examine them. Not only is he looking for secret doors and whatnot [search check], but he is trying to understand any clues the figures - what they are holding, what's being brought to them, etc - can give him. "There must be an answer here somewhere, but what? What does it mean?" he puzzles quietly.
Once again, he compares the statues to the pictures, trying to see if the clues are there.
