The parallel dimension of Elysia, located within the mysterious region of space known as the Delta Triangle, was sometimes compared to Earth's Sargasso Sea, which became home to countless shipwrecks from virtually every seafaring nation on the planet. Like the Sargasso Sea, Elysia became the final resting place for space vessels from across the known galaxy. The U.S.S. Enterprise and the I.K.S. Klothos were both trapped here briefly, breaking free only by linking their ships' systems on stardate 5267.6 (2269).
