When a mysterious mirror enters the care of one Princess Twilight Sparkle, similar to another she and her assistant Spike had gone through in the past. However, this one remained close, and had a darker feel to it. Any knowledge about this gateway had been lost to the ages. Twilight, of course, sets her curious mind to finding out the mirror's origin and just what laid beyond its frame. However, after leaving Spike alone with the mirror, she returns to find the mirror fading away after being activated, with no sign of her assistant.

Spike has been taken from his home, trapped in a strange, mysterious land filled with darkness and corruption. His body has been warped to a shape only vaguely familiar, and he finds himself with a single task: Survive in this land for one year without giving in to the corruption of the land. Only then would the gate allow him to return to his friends and family.

Join Spike on his quest in the dark, perverse land of Mareth, as he faces demons, monsters, and other bizarre creatures. Will his mind and body stay untouched? And when the time comes, will he even want to return? Only time will tell.

A crossover with Corruption of Champions. It will be featuring mostly OC characters, written to fit the world so that the story remains original and doesn't simply copy the source material.

Takes place about five years after the end of the fourth season. All characters involved in sexual activities are 18 years or older. Equestria is still pony, Mareth is anthro.

Also, thank you to Cicero Niche for giving me the title.

Fetish Warning: Basically anything that can be found in the source material will be found here most likely. All I can assure is that there is no scat, watersports, foot fetish, any other sort of 'gross out' fetish in this story. Anything else, only time will tell.
