Reginald The Bloodeye

Long ago in the frozen planes of the Akon lived the Immortal Demon of the crimson frost who slaughtered countless Akon without mercy. The Demons reign seemed to be endless until a lone warrior welding a frozen blade bested the demon and placed a seal upon the demon that only one of pure heart could break. My name is Reginald and once upon a time I was a knight of House Frost I helped defend the boarders of Umaud and The Great Wall of Frost until  the war that saw brother behead brother, sister slaughter sister. It was the most horrid example of humanity undying cruelty, I had to find a way to put a halt to this war so sought out the Demon Of The Crimson Frost and offered him a deal in exchange for freedom he would end the civil war and the Demon gladly agreed, but had I known the consequences of the deal I'd of sooner taken my own life for with the little power he had he possessed my left eye coloring it blood red and changing both my hair and right eye to a light purple. I then killed both the Council of griffon and the rebel leaders putting an albeit temporary end to the war. I and the demon battled for years for control, I knew eventually my might would fail and the demon would conquer my soul so I took my silver blade and plunged it through my heart and as I lost consciousness I looked to the sky and saw not the gods, but the demon smiling before me. I awoke to a greenhaired women preparing some sort of alchemical medicine "who are you" I asked, but the words failed to escape my lips instead I mumbled "thank you for saving me", but the voice was not my own for it was none other the accursed demon I once again lost consciousness, however this time I found my self in a black void filled with nothing, but I and the demon. "We may battle for control for your body for years to come" claimed the demon
"or I may offer you a deal"
"What are the terms" I inquired
"Simple I get your body and in return your firstborn son will be born with a heart of gold that will outshine even the unspeakable evils that I will do"
"Provided of course your second born son's heart is as noble as the first" spoke the demon
"Then it's a gamble on both sides" I retorted
"We will see who's luck gleams the brightest" smiled the demon as he outstretched his hand
