The trap must have been set near the end of the tunnel, because Korra only had to burrow for a little while before she broke into an open space. Iroh extended his light to reveal a cellar. The area they entered first was filled with dusty wine bottles and ancient, withered root vegetables, but there was an archway to another room, which turned out to be the room where the tunnel entered the cellar.

The first thing Iroh noticed was the stone statue the granddaughter had been riding -- only a statue again -- near the entrance to the tunnel, half buried in earth, and looking a little worse for wear. He hurried over to examine it.

There was also a workshop space, filled with various mechanisms which looked like they'd been flung about in a fight. The laboratory space was further on, near a set of stairs, and mostly undisturbed. There was a bottle of chloroform sitting out on the table, although all the other chemicals were neatly stored on the shelves.
