The Ring of Immortality represented one half of the Rings of Vaale, a set of two rings forged by the Architects of Vaale. Legends say that the ring bestowed immortality upon its user, but ultimately led to insanity. It was believed that its adverse effects could be nullified when paired with its twin, the Ring of Fortune, thereby granting its wearer great power. The ring was once held by a notorious space pirate spanning multiple generations of the Galactic Empire's rule, before it was obtained by a member of the Tagge family related to Ronen Tagge. Tagge claimed the ring symbolized the family's eminence and eventually, it became his.
Detta Yao, a student enrolled at the Shadow University, sought to obtain the rings, enlisting the help of the renegade archaeologist Doctor Chelli Aphra and Professor Eustacia Okka for the task. When Yao and Aphra reached the supposed location of the Ring of Immortality, which was the Workshop of the Architects of Vaale located on the world of Dianth, they discovered the ring was missing.
