Lake Astacol was the home of the Goblin god, Crayfish. It lived within the lake fed by magical springs. While Crayfish lived within Lake Astacol the Long Pearl River provided irrigation for the lands to the east. When the Olympians invaded Poseidon fought with Crayfish. Their fierce battle split the earth and the river in two. The Long Pearl River fractured into the Long River in the north and the Pearl River in the south. Tomak’nax, the city at the Long Pearl’s head was also split in two as well. Now two rivers and an eight mile stretch of soggy land separate the two halves of the city. The two halves of Tomak’nax stay connected by the Cableway, an enormous cable ferry between the two cities.

While the Crayfish deity was defeated by Poseidon, Lake Astacol remains home to many crayfish. These animals provide a valuable source of protein for the goblins of Tomak’nax. The crustaceans are caught for export as well, either alive or preserved in one fashion or another. Lake Astacol is calm, but difficult to sail on due to the bumpy low bed beneath the water. This landscape creates an ecosystem that supports the abundant crayfish, but also causes many boats to run aground.
