You know these worlds. You've been here before.

Earth, 2023. Boston
The PHL, a heroic alliance of pony and human, led by Cheerilee and Marcus Renee, are holding the line as best they can, as usual. Not much has changed since the events of The Light Despondent, a year previous. Unless you count Celestia's Barrier making landfall, with vicious armies of Royal Guard, Equestrian Army, and Wonderbolts, now more newfoal than natural-born pony, hellbent on saving humanity whether they like it or not, converting all humanity into the nigh-zombielike newfoals.

There used to use bureaus for this, Conversion Bureaus if you will, but humanity took exception to the bureaus, blew them all up, and by now, there's few humans that'd claim to support Equestria. This war is reaching its endgame, and humanity's running out of pieces.

They need a miracle more than anything...

Earth, 2030. Britain
Like Earth of 2023, they need a miracle more than anything. It's not the future of the previous Earth - it's far worse. The last humans, and their pony allies, are confined to Britain, the only stronghold of humanity, in a world overtaken by the Barrier. Reduced to outdated technologies, insane cults and experimental magic, they are besieged on all sides by the Empire of a mare that was once Celestia, who now goes by the name Astra Solamina Maxima.

In this hopeless war, their best defense is David Elliot man empowered by the magic of the British Isles, an Avatar of Albion. The last, desperate plan they have is to send him to Equestria, where he can defeat the Tyrant.

Instead, he finds himself in Boston, in a war beyond his comprehension and yet far too similar...

You know these worlds, but they don't know each other. You've been here before - but you don't know this story.

Yet.

These two worlds are going to get their miracles.

A crossover between The Conversion Bureau The Other Side Of The Spectrum and The Avatar of Albion. You know you wanted this.
