Iron Lung: Depths of Despair - An MLP Crossover Fanfiction.

"This is not an expedition, it is an execution. When they put you in here, they don't want you to return. And even if you do, and even if they keep their promises... what freedom waits for you? A few dying ships in a sea of dead stars?

If there still is hope, it lies beyond the veil. Hope in this void is as illusionary as the starlight. I will choose to breathe my last here at the bottom of an ocean, unseen, unheard, uncontrolled.

They will get their execution.

I will get my freedom."

In the wake of the Quiet Rapture, a cosmic cataclysm that silenced the universe twenty years ago, darkness reigns supreme. Ships and stations drift aimlessly, cut off from their homeworlds, lost to the void.

Twilight Sparkle, a convict aboard the grim fortress known as the Consolidation of Iron, faces a fate worse than imprisonment. Sealed within a decrepit submarine, she is thrust into the depths of a desolate moon, where a blood-red ocean awaits-an ocean that defies all logic, its crimson depths teeming with unspeakable horrors.

As Twilight descends into madness, she must confront the terrifying truth lurking beneath the surface-a truth that threatens to consume her sanity and unleash unimaginable terror upon the cosmos.
