Heralds Of Orcus
Lake Wintermelt isa permanently warm lake north of Winterhaven. It supplies a lot of food for the Nentire region. Inhabited by Sahuagin and Orcs, it can be a dangerous place to go, but the journey is worth it for the excellent fishing.
The Lake's heat is provided by an elemental force deep within a cavern system below the waters. This was recently corrupted by agents of Orcus with dire results, but has subsequently been cleansed by the adventurers.
