The USS Spectre was entered into service in 2376, part of fleet regrowth following the Dominion War. In 2380, the Spectre came to the aid of nebula-class vessel USS Leviathan, which fell victim to the formation of a black hole among the Sloane nebula.
In the chaos, both the Spectre and the Leviathan suffered heavy casualties that lead to the merging of both crews. The Leviathan’s computer core was salvaged from its wreckage, though the Leviathan crew claim that the core is corrupted and partially sentient, how it survived the disaster remains a mystery. In addition to its troubling core, the Spectre is thought to be cursed by the tragedy suffered by its combined crew, there are tales of an unsettling presence and whispers in its corridors.
