Nars swallows a lump in his throat at the carnage. He mumbles while bent about his work, "Some creature. Hmm. Looks like it, er, escaped." He raises an eyebrow at Nestiphae (or tries to, he can't do it) and says quietly, "Erhem, still want to, er, come?" He examines the relief in more detail, looking for any levers or triggers (Search +9, +2 for secret doors, +2 for unusual stonework). He also checks out the area near the pit trap for structural damage and for any more clues about the creature. He'll leave the decision whether to press on or try some more at the previous doors to Percy.
