It was not something you expect to find in an abandoned tower, a set of zoo cages. The first one held three skeletons of what the ranger said were bears. It had some sort of trap in front of the cage, but our scout was unconcerned with it, until he stepped in front of the cage and in a flash of light was changed into a bear and then the floor raised up, the cage door opened and he was dumped inside. We stood dumbfounded as the cage locked behind him.
