Abraxas

Abraxas' past is largely unknown. What is known is that he is old enough to have watched the birth of 'the universe' as he survived the Barren Plague that came afterwards. Another thing known is that he took on the rank of Devil at that time after the previous Devil died off, being the strongest demon left alive. Even after demons began to rebuild, he gathered more and more power, defeating any demons attempting to challenge his rank.

A lot is shrouded in mystery during the time of the Plague and the discovery of humans. At some point he and the leader of the angels, Solaris, had gotten into a reality warping battle over this new species, with Abraxas blaming them for the Plague and wanting to eradicate them while Solaris defended them, saying it wasn't their fault. It isn't known how long the battle lasted, but eventually both demons and angels stood up as the Boundary of their very dimensions were crumbling from the immense power the two were expelling. Being brought to reason got them both to reluctantly call a truce in favour of not killing more of their own, accidentally or otherwise. A rift had developed further between the two leaders, each barely keeping in contact for some time.

Barely a few months passed before that rift tore completely: the day Solaris attacked him without warning or reason, permanently tearing his wings from his body. In unimaginable pain, betrayal, and shock, he launched into the Overworld and attacked him. Hundreds died in moments, leading into a full scale war that lasted for many years. With every day he grew more cold and rageful, a state which never fully left him even after the fighting was brought to an end by the threat of dimensional instability once more. With further years needed to recover and rebuild again, the two dimensions were truly cut from one another, seemingly permanently. Many, many years pass, and new generations of angels and demons grew to hate one another as well.

Many things happen, much research is done, and eventually Abraxas comes to lose his hatred for humans, especially after finding out how weak and slightly pathetic they are. Something changed however when a new power is born into the human world; a tiny little human with the ability to cheat death, as he can. He had thought it impossible that such a weak creature could hold that power, and grew intrigued, watching over her as she grew up without knowing of this. As the years continued to go by he saw her grow, gain more power with her second ability, electric manipulation, and decided he wanted to see how her soul would return after death. He sent low-level demons after her as tests, wave after wave to see how she handled it; when they failed, he sent mid-level demons. It was sudden when he felt the power shift and knew she had been killed, going over to confirm. With that slightly annoying research subject out of the way, he awaits her eventual return.

Over 200 years pass; one day, while going about his day as usual, he received word from a subordinate that an interesting group of humans had found out about demons and were quite adept at killing them...and that one of them was living in a void of her own, electricity wielding; a split soul to another. Knowing instantly that this was the one he had ordered killed, returned after all this time, he sends out a final challenge to this group; a high price was to be put on their heads for demonic bounty hunters to try their luck. If they survived a month, he would meet with them and grant a single wish each, along with forbidding further demons from hunting them again. It was time to deal with the pesky but interesting human, one way or another...
