"What hope will there be when even the wrath of angels cannot be quenched?"

Following the unexpected death of King Rhosus II, Griffonia descends into absolute chaos. The nation splits into two factions, Northern Griffonia and Southern Griffonia, and the threat of civil war is all but certain.

But a young griffon with a deep hatred of ponykind attempts to stop civil war from happening, and unite Griffonia under a new imperial banner. She wishes to bring back the glory her ancestors bestowed upon her kind, which the ponies squandered and beat into the dirt with their filthy hooves.

When an old enemy emerges with a force unlike anything seen in history and threatens the destruction of ponykind, Princess Celestia reaches out for some more… otherworldly assistance.

The lines between friend and foe blur as angels rely on demons to fight for the survival of mortals, and the world of Mundus will truly never be the same.

[Alternate Universe tag isn't quite as obvious as the others. Less of a radical change as in other fics, more like changes to history and occasional stuff that's been determined in the show]

Any OC's within this story that I haven't created (Sunshine, Iridia, Rhosus, etc.) belong to their owners, even if they aren't copyrighted, I'd still feel bad for not crediting them. Bellum Millennium is a sci-fi universe made by me, but it'd be pretty pretentious if I copyrighted it since it's free.]
