" The Fang in charge beckoned to the trolls, but the trolls shook their heads. The Fang pointed at Janner and Tink and brandished its sword at one of the trolls. The troll shook its head again, but with less certainty. Finally the other troll nodded and released its grip on the wall. The other followed suit, and the two beasts stepped to the edge of the long stair bridge that led directly to where Janner and Tink knelt. "
