But now evil is winning.  Dark spirits cross from the demon realm into the corporeal world, spawning malicious imps and monstrous fiends.  Humans unwittingly fall prey, physically and emotionally, to these forces of evil.  Their despair and hatred feed the darkness, spiritually terra-reforming the earth so the demons will one day soon be loosed from their realm, invade ours, and directly attack the gates of Heaven.

Angels and the dark djinn possess human souls to wage their never-ending divine war, oblivious to the collateral damage.  But down in the trenches of our cities, a band of immortal warrior brothers knows the real price, and pays it forever in blood and pain and demon ichor. 

These warriors – the talyan – are also possessed, by repentant demons.  The only redemption for the demons and their soul-torn hosts is to fight in the endless war.  Reviled by angels and dark djinn alike, these talyan bury their diverse pasts and their fierce passions to save humanity from the hell-spawn.

Then the first female talya appears, and everything changes...
