A one-shot prequel story to Fallen Sun
(Go check that out too!)

Prince Uriah had grown tired and anxious. Despite his adventures and victories, there was just something missing. He began to question, in spite of all that he did, if he really ever made a difference in anypony's life. That's when he met Scarlet Thorn, undoubtedly the wildest and strangest pony he'd ever know, and certainly one, he'd learn, he couldn't live without.

From the deepest reaches of the cosmos, a force is gathering. The infinity gems are being gathered once more and if the gauntlet is empowered again, the pure annihilation will follow. Every thing that exists in all realities is on the line! Only two beings stand against this threat. Twilight Sparkle, princess of magic and Equestria's greatest hero, and Dormammu, all-powerful magic despot and Dread-lord of the Dark Dimension! This bizarre duo will journey across the multiverse, traveling to incredible places, facing foes both good and evil, and wage a war to end all wars. That is...if the Dread-lord can keep his darker tendencies at bay long enough.

The abandoned infant's cry is rage, not fear.
~Robert Anton Wilson
A week into Twilight's role of princess and all is at peace. She adjusts to new duties as a princess, while still keeping up with her friends and her books. However, the sky is always calmest just before the storm. An innocent outing planned for an astrological event seems to send a look of unspeakable terror into the eyes of Celestia.

A reckoning half-a-millennium in the making is about to crash into Equestria and it will put the bonds of harmony to their ultimate test.
