In the beginning Alexander was crafted and born as a set of two.  His mother, a succubus, pick and chose certain traits from her various lovers to meld into a creature she thought would be superior than each.  From her machincations the Brothers De'vir were born.  Alexander the older by a few hours, and Matthew the younger.

 

As Alex grew, it was clear they were something unlike their mother of fathers.  Shadow wraith demons of the utmost potency is what they had become, with subtle changes that had them outmatching their family in almost every aspect.  It was a home full of demons, but it was a relatively happy home.  Little did Alex know that his own choices would eventually set them on the path to ruin... though where it put Alex, either destroying him or letting him live for the first time, has yet to be determined.

 

Decades passed and the brothers grew ever stronger.  The drive to continue to new heights drove Alex's lust for consolidating the gifts of others.  With the ability to bond to nearly any mortal creature he symbitoically grew.  Traveling the world in this pursuit he eventually came upon Japan some centuries ago.  There was a war brewing between the Elven armies and a powerful Demon Lord who was subjugating the demon population to his own ends.  What better place to take from others, than at the precipice of battle where the strongest would be there for the picking.

 

During a session of absorption Alexander came across something very unexpected.  There was a  boy in his early teenage years attacking a congregation of demons... and winning.  Alex watched on as the boy fell enemy after enemy with small flares of uncontrolled magic and strength.  But the boy's lack of training was obvious as he sustained blow after blow, eventually weakening him.  Alex then approached as the boy lay bleeding, and no doubt would succumb to his wounds.

 

The boy's hatred was pallable, his eyes angry and disgusted by Alex's demon form.  His shadowy presence coasted along the earth, but not to slay the boy, but with promises.  Alex offered to bind to the boy, to give him the strength he needed to reach his goal... which surprisingly was not unlike his own.  To kill the Demons, and especially the Demon Lord.  Finally the boy gave up his life and Alexander took it.  He bound the boy, gaining his affinity for Magic, and the boy gained strength unlike he had ever known.

 

From there Alex used his gifts, ones for combat and knowledge, and trained to the boy as a sort of champion.  With his natural gifts, a human, a half elf, infused with his demonic power:  The boy would be a powerful ally and very few would be able to stand against him.  That decision would haunt him.

 

Several decades later the boy, Camthalion as Alex came to know him, began to grow increasingly irate.  In the belief that Alex and his demon family were threat, Cam killed all of them save for Alex and his brother Matthew.  This marked a turning point in both their lives.  Matthew felt inferior and continued to chase power... Alex felt guilty and he too chased something:  redemption.
