The year is 2359. Ponykind is on the brink of extinction, with the ruthless and merciless army named the Hexaband. Their last attack, the invasion of Exiumm, has left Ponykind on it's toes. A ship named the Dawn of Time escapes destruction, as it uses faster-than-light speed to escape the now dead planet.

Hexaband forces have followed the Dawn of Time, and have fired upon them. Lily, a KNIGHT-II Super Soldier escapes the Dawn on an escape pod, aiming for a ring world. Once they land, they begin to discover terrible secrets, and the dark intention of what the ring world actually is.

This. Is Halo: Equestrian Fall.
