Oshiego the abyss

He evolved with the gift of flight
Unaware of the abhorrent crime
The King's top lieutenant turned conspirator
Approaching Armageddon
Casted into the Lake Of The Dead
For his impertinence he was doomed
Swirling vortex of demise
Mutilated flesh and blood
Now reborn, a devourer of souls
Destroy!
An eternity, he still survived
Burnt flesh and broken wings
He was saved by the Elder God
From eternal damnation
Offered a chance he couldn't refuse
To avenge his death by Kain
Blessed with powers to helm from different realms
To slay his former brethren
He was thrown into the abyss
Calcined skin and ruptured bones
Excruciating agony
Descend through an everlasting fire
