The Architects' Mausoleum, a crypt situated below the city of Vaale on the planet Dianth, served as the ultimate burial site. Within it rested the Ring of Fortune, a significant artifact among the Rings of Vaale crafted by the Architects of Vaale. Eustacia Okka, while part of the crew led by the renegade archaeologist Doctor Chelli Aphra in their quest for the Rings, unearthed the Architects' Mausoleum and subsequently acquired the Ring of Fortune.
