Shadehouses were facilities of the Seekers program in the Unknown Regions Chiss Ascendancy nation. The goal of the program was to train and prepare young Chiss girls with abilities known as Third Sight to join the sky-walker corps and become sky-walker navigators for the Ascendancy's Expansionary Defense Fleet. A number of Shadehouses were located in the Ascendancy—including the Seekers' Shadehouse on the planet Ool, and the Thearterra center located on the terrestrial astronomical object Thearterra.
