Born in a secluded and secret Grim kingdom called Occulton, Occultra's intensely over-protective to the point of physical punishments and magically-metamorphosized arachnid father kept her from leaving the kingdom, telling her that the world outside the kingdom would never accept her because of their race and that Empirids commonly practice Grim Magic. Occultra's only hobby was said magic. However, the kingdom came to be attacked in a desistating and merciless raid commited by soldiers under the command of a despot calling himself 'Azzhole'. Occultra's father died protecting her from the raiders as she was left hidden, but seeing the brutality all the same as the crazed raiders joyfully in a sadistic way torment the Empirid Grims, even going as far as to treat it like a game as the same thing happened to Occultra's other family members, her mother, unlucky younger and older siblings, even an innosent pet Troggle pup that barely begun to live for being owned by Grims. Occultra was left with a destroyed kingdom and her stuffed Barbear that was given to her by her mother, left orphaned and miserable. Desperately trying to find the power to bring them back, she began to harness Grim magic more and tried to turn her family into Grimaces, creatures that're often products of Grim Magic. Though successful, they only came back as mindless unsentient creatures that, though they obey Occultra's command, they could not replace the family she lost. Occultra began to be consumed by grief, sadness and anger, as she was left trumatised and confused by the cruelty that was allowed to run rampent. She came to be adopted by the then council member Hertzburg in secret in a bid to protect any surviver of the raid.
The grief of her failure, the hatred brought from the cruel world, and the guilt of only bringing her family back as Grimaces, were all far too great for her and her magic was tainted by such a blackened heart and mind. She came to dispise and hate the world Azzhole created, and could not bare the cruelty onto Grims and Empirids because of history not even related to Remena. Her newfound power was slowly manifesting and she eventually discovered she was the true definition of Grimsistery, having the power of a villain but the deeper heart of a hero. She was neither good or evil in traditional senses, allowing her to be enlightened and fully corrupted at the same time to the point of neutrality. She knew immediately what she had to do: do both good and evil in order to heal the cruelty and bring balance to Remena. Thus Grimmess Occultra was born.
Occultra organized a powerful movement of those under cruelty to begin her amoral campaign of healing the darkness of the world through turning cruelty onto them. She chose four favorites: her bastard daughter Tephra which came from a rapist who manipulated her to vilify her race and paid for it with his life, a murderous scorpion-like Empirid named Tirade whom she adopted since his murderous rampage brought on after being shunned and abandoned by his own orphanage in a Empirid-hating town, a Creijud former supporter of Occultra's enemy named Scorian whose wife was killed by Azzhole, though he blamed Celestius because the soldiers said it was "Under Mage Council Orders" and thus had the wrong idea that it was Celestius' doing, because of befriending Grim neighbors, thus he drowned himself in Grim magic and became not only powerful in the process, but also completely incapable of speech and feral, and the now former member of that same council, Hertzberg. They helped build a powerful Grim movement against Azzhole's reign through the illusionary evil and false deaths for the sole purpose of getting everyone to realize the true evil.
