Over the nights, Princess Luna has been quite content with her standing as co-ruler of Equestria, even if she believes she's merely assisting her elder sister.

Recently, something catches Princess Luna's attention from the Everfree Forest. It felt unnatural and odd to her, so she sends her guards to do some recon in the forest, and what information they come back with caused the Benevolent Moon Goddess to investigate by her lonesome.

In the wake of Discord's return to stone and a restored peace to Equestria, the world is again plummeted into darkness as an ancient, forgotten evil returns. Celestia and Luna quickly find themselves forced into a deadly tournament, as Twilight and her friends race against time to save them.

Although this story features Pen Stroke's Nyx (Past Sins), this story itself is not related to Past Sins, nor does it require a reading of Past Sins.

When Twilight plays with magic beyond her control, she finds herself and Rainbow stuck in a strange, horrible world. When they find out what happened, will they be able to get home? Will they even want to?
