Sonarg is a region dominated by large lakes and forests. The forests have long been home to wild xenophobic elves and dangerous plants. The lakes have plentiful fish, but also hold deadly serpents and other horrors.
In the Lith-Crillion Era, this region was settled by the githzerai. In the First Suellk Invasion (135 HE - 150 HE), the githzerai were subjugated by the illithids. This land then became territory of the Suellk.
