The Leviathan

The Fading Lake and the Drowned City are not deep bodies of water for the most part, but there are deep parts. And in those areas, sink holes and trenches, buried caverns formed of sunken bits of a long past golden; here the Leviathan makes its nest.

Most of the time, the Leviathan is content to remain hidden beneath the waves, feeding upon whatever has left the scars in its mutilated hide. Most of the time. Some of the time, the great giant sea monster explodes up to the surface and devours settlements on the Coast. Like the Behemoth, the Leviathan is singular. There is no more than one to bear the name. Unlike the Behemoth, the Leviathan is predatory, and those sentient beings that it devours it certainly does not devour by accident.

Unlike the Behemoth, there are not structures on the back of Leviathan that the Psychonauts might plunder. But when the Leviathan is active, the ancient underwater tunnels and structures where it normally sleeps are open for exploration by the bold and near suicidal. But psychonauts should be wary. The Leviathan got its scars somewhere.
