Kill the Dark Multiverse

As the conflict between the Empire and the Revolutionary Army, a third force has come into the forefront and all conflict ceased to a far more dangerous threat on the horizon.

Whoever they are, they are being magnitudes far more powerful and far more dangerous than anyone could think as they easily destroy every opposition in their wake and are all immortal unkillable.

They call themselves, the Dark Knights and they have come to these world for whatever reason known only to them.

As enemies turned to allies as revelations and betrayal are at an all time high, the world's only last hope, other than its defenders, are two figures...

Who both dressed as a flying rodent or an avian that flies only in the night.

And the reveal that the main conflict is bigger than they could have anticipated.
