Titan Rift - OP MC LitRPG

Unregistered Primarch Warrior is launched out of the universe while killing a Warp False Deity and into a new world that has screens, systems, and access to magic he never thought possible.  He falls from the sky in a fit of fire and flames onto a blue planet.  A new center of humanity? Races that look so familiar yet act so different.  An entire planet of habitable life ten times the size of the myth he once heard called 'Earth'? Rifts that spew monsters by the thousands? Just meant Aethernus Vhal had more to kill in his Endless War.
