It took several minutes for unenhanced eyes to adjust to the darkness. When they did, Sam saw that he was standing in a sort of antechamber. Gray Otter and Harrier were there, too, but Jason had probed deeper. More aboriginal pictographs adorned the chamber’s walls.

Harrier identified some of them, speaking their names as though they were totems: Kangaroo, Koala, Bandicoot, Snake, and, arching overhead, Crocodile.
