Sarrukh

The sarrukh were a race of reptilian humanoids. They were one of the five progenitor, or Creator Races. Eons ago, they built and maintained empires across most of the continent. In present day, these ancient and evil creatures were almost extinct. Most sages who knew of the sarrukhs' past glory simply referred to them as the saurians, the sauroids, or the progenitors of the Scaled Ones. The sarrukh have left a lasting legacy: the racial diversity of the scaled races in the world. They took the scaly, reptilian animals and monsters native and modified them into sentient beings such as the yuan-ti, nagas, pterafolk, asabi, lizardfolk, troglodytes, tren, and many other Scaled Ones.
Millennia ago, the sarrukh dominated all of the continent. Their mighty empires were the first in the world, encompassing the jungles along the southern coasts to the eastern shore and western shore, The sarrukh enslaved or sacrificed other creatures in the name of their god, the World Serpent.
Problems of their own making eventually caused the sarrukh empires to crumble. This created a vacuum in which the sarrukhs' created races rose to prominence and established power centers of their own – many of which were still active to present day. However, the sarrukh have still managed to remain relevant in modern-day. Despite their small numbers, they still command the loyalty and respect of the races that they had created. An immense rift has formed between the surviving sarrukh clans, and the enmity among them could lead to open warfare between the scaled races.
