Leviathan of Dis

The 'Leviathan of Dis' is the name given to a gigantic corpse recovered from a crater on Jartar in 2163. It is believed to be the remains of a genetically engineered starship and its age was originally placed at nearly a billion years old.

However there was little time to study it. Not long after its discovery by a batarian survey team, a batarian dreadnought visited the Dis system, after which the Leviathan mysteriously disappeared. The batarians have since strenuously denied that the Leviathan existed at all. They become even more vocal when showed documentation of the Leviathan by salarian researchers before its disappearance.

 * The Leviathan of Dis is possibly a reference to the early 2000s SciFi Channel series Farscape, in which the main cast traveled aboard a sentient ship belonging to a species known as "Leviathans."
 * It may also simply be a reference to the fact that any being of gargantuan proportions can be referred to as a Leviathan.
 * The Leviathan of Dis may also be a reference to the organic ship found in the episode "Tin Man" of Star Trek: The Next Generation.
