Somewhere below the sea, there lies a city.
A city envisioned to be the home of invention, of progress, where the finest minds of all of ponykind would be allowed free-reign, and so reach a potential undreamt of on the surface.

Yet something has gone terribly, terribly wrong, both with the city itself and it's inhabitants. Now, only abominations and the keening wails of the damned inhabit the once bustling tunnels and domes of that great place, and of all thats left of it's former splendor there is only rot and rust.

Is it possible to escape such a nightmare? Is it at all possible for an individual to survive such horrors, such insanity, without being tainted themselves?

Perhaps that is the only fate that await those inside; to die under the waves, alone and forgotten... or to leave a monster.
