At the bottom of the Mariana Trench, a silence so profound that it could crush the sanity of any surface-dweller reigned. Darkness enveloped the water, a realm where sunlight dared not reach, and the pressure could pulverize steel. This was the place where life thrived in impossible forms, and where A single Doctor made his home.

Leviathan had long lost track of time. He remembered the surface, once. Before his transformation. Before he became something other. His skin had once been smooth, unmarred by scales, his limbs symmetrical, unmarked by the aberration of his third arm.

At first, he had been an explorer, a man of science fascinated by the ocean’s depths, lured by its mysteries. He had joined an expedition, one meant to plumb the furthest reaches of the ocean, to understand the uncharted depths. But somewhere along the way, he had become separated from the team, his submersible lost in the endless trenches.
