The Oroko

The Oroko are a nation of Lizardfolk that the Drow fought and mostly destroyed in a great war known by the Drow as the War of Palath Nenui, when the Drow leaving Silethil began to inhabit the swamps of Palath Nenui. The Oroko still inhabit the swamps there, along the fringes of Sivaria and into Northfoot Forest and in wandering groups, disunified and broken. 
The Oroko Lizardfolk are more slender and smooth skinned than the Môrfell Lizardfolk, but have a range of varying colors. Some are solid green, others are a dark brown with tan stripes from head down to the tail, while others are black with a tan chest and blue tails.
