Rattatak is an Unknown Regions world located in the Guter Wade system orbiting the star Rek. The planet is noted for its squared-wall canyons and arid gullies; its red rocks are the colour of spilled blood. The native Rattataki are thought to be descendants of a long gone Republic pilgrimage, while the remainder of the world's population appears to be drawn from other worlds in the Unknown Regions of the galaxy.
