Every 20,000 years, the comet of Hungaar returns to the skies of Equestria, seeing it is considered one of the greatest things a pony could witness in their lifetime. However, the comet's return brings forth a black scourge on the land...

In a desperate plea to the hands of fate, the Unicorn Starburst Nova casts a spell which summons a warrior of great strength from beyond the world of Equestria. Mysteeri, a Witch with extraordinary strength, is brought forth from a crack in the sky, her powers unlike any magic seen in Equestria's history.

However, with Hungaar getting ever closer and Mysteeri's existence conflicting with this universe, time itself is against them. This time, friendship alone won't save us.
