TRIGGER WARNING: Contains a brief sequence of brutal rape. TO SKIP, avoid red text.

Thousands of years ago, six ponies wielded the power of the Elements Of Harmony. However, they let the power overwhelm them and succumbed to it, using it to spread fear and darkness across the land. Led by the cunning Arcane Rune (Element Of Magic), she and her group consisting of Rebel Bond (Element Of Loyalty), Fable Fidelity (Element Of Honesty), Grim Glee (Element Of Laughter), Vanity Grace (Element Of Generosity), and Callous Courtesy (Element Of Kindness) set out to hunt down a group of ponies who may have managed to discover their only weakness...

This one-shot focuses on a small camp who are attacked by The 6 and killed in brutal and disturbing ways.
