Leonek and
Lucius carried
Brook into the cave entrance, followed by
Chad,
Tobias,
Story, and
Elizabeth. The tunnel sloped gently upwards into a cavern where very little sunlight penetrated from behind, but their torches gave a good view once they surfaced. The tunnel opened up into a large, round chamber. Once he emerged from it, the water was only about two feet deep. It surrounded a raised dais of dry land in the middle, as if it were a moat. On the platform stood a rectangular altar made of obsidian with horns on its four corners. Three additional tunnels led out of this room. The one in the left wall and the one in the right wall both sloped downwards, where the water got deeper. There was another tunnel opposite the one through which they had entered. This one slanted upwards, rising out of the water.
On the dais stood two green, scaly creatures. One of them was eight or nine feet tall, and the other merely seven. Both of them wore long mesh vests that appeared to be made out of silver string. Their huge webbed hands ended in sharp claws, in which each of them carried a long spear and a weighted net. They had gills on their necks and large, bulging eyes, and they had features that seemed to be a combination of various aquatic and amphibian creatures.
Elizabeth couldn't help but be reminded of the Gill-man from
The Creature From the Black Lagoon, a movie she had seen not long before she had joined the TARDIS crew.
Brook had to surface immediately, as she was out of air. For a second she thought the big one was looking right at her, but it didn't seem to notice her yet. However, they wouldn't be able to miss the torchlight.
