Sorry, that this is really short, however, it is just a prelude. Future chapters will be much longer. I had a lot of help on this from FunnyBunnyWarrior, my beta.

Scaren just managed to dodge the blade of the rapier of the erinyes before him. The erinyes, her wings batting animatedly; a stark contrast to her lithe human-like form. She held the rapier to her side, as if to strike again.
Scaren cried aloud, a flaming full blade materialized from a vault hidden deep in the shadows of the Underdark and, into Scaren's outstretched hands. He slashed at the devil, and with a glancing blow he managed to create a gash on the erinyes' blackened armor. Where the weapon touched, it left behind a trail of singed metal. Smoke wafted from the singe marks, rising into the stale air. The attack left Scaren vulnerable. His arms were wide as he tried to steady his balance.
That was the moment she was waiting; all the time she needed; all the weakness he needed to show. With rapier in hand, the devil thrust her weapon forward. She struck true; the thin rapier finding a crack in Scaren's breastplate and fitting through. He was lucky in that the rapier bounced of his ribcage, missing his lungs, but unlucky in that it cracked the ribs. Holding his chest, he gasped for breath.
The devil struck again, more furious and swift than any other time. The weapon clanged as it bounced off of Scaren's armor. The impact drove Scaren backwards. He stepped back, and realized too late his mistake. Feeling no ground beneath his feet, he panicked as he fell from the rim of the cliff.
"Damn bastard," the erinyes hissed as she flew away, her wings thrashing a steady beat. She left Scaren to his fall.
Scaren fell, the weight of his armor making his fall faster. As the spawn of a devil and son of a celestial, Scaren understood well what death meant for him.
