After the proclamation of the Alliance of the Crystal, both Gelflings and Podlings were assumed as staff in the Castle, with the former serving as guards and the latter performing the vast majority of the domestic work, serving as cooks, servants, musicians, animal handlers and even massage therapists to the Skeksis. The Skeksis took control of it and modified it in accordance with Garthic principles, presenting themselves as the successors to the urSkeks. The Castle, modified in the Garthic style, during the stewardship of the SkeksisĪfter the Great Division, the Castle's crystalline structure stopped shining and took on a dark hue, being covered with a stone-like substance on the surface. When Raunip discovered the true origin of the urSkeks, he riled the Gelfling to attack it and reclaim the Crystal, but was stopped by his mother, Aughra. It emitted a constant light which was felt by all of Thra, and its song was known even where it was inaudible.

The Castle was built by the urSkeks at the start of Age of Harmony on the site of a mountain enclave housing the Crystal, and was modeled on their own homeworld.
