The Lothal Key Stone was a stone relic. One face of it showed a triangle containing four hands: one clenched, one clenched with a pointing finger, one open and firm, and another open and relaxed. The Force Priestesses, the Force wielders, and the Lothal Jedi Temple were also represented along the triangle's edges. The opposite face displayed complex patterns of three smaller triangles bisected by three semi-circles. Within these smaller triangles were even tinier circles, each with lines extending outward.
Minister Veris Hydan, an advisor to Emperor Palpatine, examined the Lothal Key Stone. Hydan's mission was to uncover the secrets of the Lothal Jedi Temple, with a focus on gaining entry to the World Between Worlds, a mysterious realm existing beyond the constraints of time and space. During an incursion that resulted in the capture of Sabine Wren, Minister Hydan activated several holographic displays of artifacts he had found within the Jedi Archives, including the Lothal Key Stone.
