Contradiction perfect combatants

They are the constancy
The final evolution
This is the last conception
That God has done
Built for eternal combat
A war that still remains
The end of destination
When all is gone
Fight, kill, blood and gore
The quintessence of war is what they're living for
Pain, death, they don't mind
Pure bloodlust, raging blind
When factions will collide
The violent spawn
Still rages on
To kill the dawn
They fight a war
The iron creed will sow the seed
All that we bleed to fight a war
The violent legacy
Eternal loyalty
Surrounded be devotion
They're marching on
One closing intervention
Unending desolation
Last act of wickedness
Before he is gone
