In this version of Equestria, the vibrant and whimsical landscape now mirrors the vices and challenges of human kind. Ponies, pegasi, and unicorns struggle with issues of power, greed, and social inequality.

When a chapter of the Sisters Sororitas, a resilient order of warrior-nuns are pulled into Equestrias underground hollows, they find themselves facing a dire confrontation with the subterranean dwellers. These skilled warriors engage in a fierce battle against them to defend themselves and seek a way to escape.
