History and specifics[]
In 2265, the Federation starship USS Enterprise visited Orthoo. During their visit, Captain James T. Kirk provided King Yo with security guards to protect the Great Eye of Ara, a holy relic. The giant ruby disappeared during their watch, and Montgomery Scott described the incident as almost costing them their necks. (TOS comic: "Furlough to Fury")
