Theory for Bellroc / Skrael fanfiction :
Bellroc is ToA 's Stevonnie. So, was once the two siblings Bellva ( girl , cisgender) and Alaroc ( boy, cisgender).
They worked with dark magic ; they aspired to leave behind their primitive ways and inferior tribal life / tribe , to become very wise and powerful , to be as they are now . ( Both asexual).
Except , they were working with the only kind of magic they knew, calling on the only supernatural forces they'd learned would help them . Their parents had passed on this unholy culture to them. One day, an Akiridion ship crashes just outside of their village. They go there, and find that the two adults are dead, they shielded their daughter from the impact and died to save her life. She was a royal Akiridion , name was unisex :" Skrael."
But , when Bellva and Alaroc tried to get her accepted into the community to help her , she wasn't welcome due to being something unknown , alien and therefore frightening, abominable.
So, they used their magic to transform her , and she became almost fully human, except for her ice blue, Akiridion eyes. Also,they unintentionally made her intersex , she then identified as a " he" or " they ".
Kept his Akiridion eyes, hair, and body shape. Had bluish, super pale skin.
Hid the hair with the outfit the siblings gave him to wear . He couldn't do any magic though. One day it was winter,and he went out to find a lost animal / whatever. He died ; Bellva used her pyromancy and Alaroc his calokinesis to find the body .
They made a deal with some great yet evil force : Give us back Skrael, and we'll serve you forever. Of course, there was a little clause in this deal. They would be reborn, and would have to leave behind their former lives, their humanity. In exchange for their service, they would also gain great supernatural power .
So the Whoever gave them back Skrael, but Skrael was different. Immortal, capable of flight and teleportation, and more Akiridion looking. He was shocked ; Bellva and Alaroc were no more, and in their place stood ToA Universe Stevonnie a.k.a. Bellroc. So the two sorcerers went off, their new purpose to keep the balance between the worlds of magic and mortals. They were as morally ambiguous as the power who had recreated them, but sought to do good.
They made themselves staves , and gained new magical abilities. Then, they teamed up with Nari , who thought their ideals were good.
They formed the Arcane Order,and made themselves a Fortress.
Long story short... post - Wizards, Bellroc dies , digested by Gatto. Skrael doesn't die , don't know how. He remembers who he was before,and regrets his life as a sorcerer. He gets a redemption ...
