*thinks*

Head back to the carving room, and try touching the carving. Make sure the Acupuncturist is ready in case touching the carving results in impalement.

Edit: new plan:

Head north to the carving room. Walk up to the carving. Turn 90 degrees left. Take one step forward.

Edit: even better plan: Summon a Mythslayer, and get it to walk off the walkway instead of us.
