Wide and vast, Turtleback Lake is named for the numerous small islands that have formed inside the lake. Viewed from the hills of Windsong Fjord, the islands look like the backs of turtles laying in the water. Although none are particularly large in size, some islands are frequented by deer and elk that swim across from the mainland to eat. The shores of the lake are both sandy and rocky, but provide easy access to the fish-filled waters. The lake is the life source of the entire Snowmarch Expanse, and it is not uncommon to see other creatures lurking in the wooded forests along its shores. The lake is so large that it would take a wolf two or three days to completely walk around it. For strong swimmers, swimming from one island to another is the fastest way to cross Turtleback Lake.
