There was a battlefield in the world, one that not many knew of. Only two kinds of beings were allowed inside that field's hallowed grounds—demons, and angels.
Rain of blood, a river of corpses, or mountains of heads, those were nothing out of the norm in that place. Not to mention, even the weakest creature on that battlefield was said to be a Tier 7 being at the very least.
In that place, millenniums ago, a battle took place. Thousands of giant demons faced their archnemesis, creatures with wings of light, in a battle for survival—a battle of hatred and strength.
There was a very ancient tale about that battle, one that not many remembered in this age. It was about a demonic armor, used to slay all the angels in that great war zone. An armor that slayed thousands upon thousands of Tier 7 beings!
It didn't even need a host to use it, it was alive on its own!
In fields where angels dare not tread,
And demons rise from crypts of dread,
There forged in blood and ancient strife,
A war-bound armor came to life.
