my fusion system: fusing weak soldiers with direwolves at the start

Betrayed. Exiled. Murdered. Reborn.
In the war-torn land of Glory, power is everything and Duke Merlin's bastard son has none. Cast out to a starving border town beside the cursed Devil Forest, Kaelor and his mother were meant to die quietly.
But when assassins take her life and leave him bleeding in the mud, another soul awakens within him one from another world.
And with it, something else awakens too...
The Fusion System.
A power that lets him fuse nearly anything.
Fusing one starving soldier with a dead direwolf gave birth to a Dreadwolf Trooper.
Fusing one hundred wild dogs produced the monstrous Cerberus.
Fusing two crumbling forts created a living fortress bristling with autonomous ballistas.
From broken men and dead beasts, Kaelor will forge an army the world cannot understand and a dominion no one will dare challenge.
