Aureole, the Shining Ring (輝く環（オーリ・オール）,Orri Orru?) is the "Space" Artifact of the Sept-Terrion, and the core of the floating Liberl Ark city. Specifications unknown, legend has it the ring can "grant infinite wishes". It functions as the city's master computer, fending off all that harm it with its judgmental self-defense mechanism.
It was briefly mentioned in the FC Final Chapter by Alan Richard, as part of his final plan. But in Trails in the Sky SC, it fell into Georg Weissmann's hands all according to his manipulation, and eventually turning him into the rampaging final boss.
