alright so heres kinda the rough version of the story: bryll was born into a commune owned by a narcissistic maniac bent on ruling (common thing for the other world eh ehhh heheh) and he knew that he could use religion to
bend people to his will. so he invented his own form of Averism and claimed it as the “right” religion, and used it to recruit religious zealots and anyone who was in need of help/answers to life’s questions and stuff
the way cults typically go. so when one of the women in the commune gave birth to an MC baby, he saw a golden opportunity to claim that a messenger of averus was just born and the baby was a holy being of some kind
and the people there totally bought it and treated bryll as some kind of messiah. meanwhile, kid bryll was like “wait what im not any of this what are you all on” but of course the guy in charge hushed up bryll by distancing
the kid from his followers. he also taught bryll their healing abilities, because “you’re a holy being you need some kind of good magic or nobody’s gonna buy it” and used this weird-looking kid with magic healing powers to
recruit more followers. then the *actual* followers of averus caught wind and didn’t want this cult getting any more influence than it already had. So they came in all white-knight style and arrested bryll and the leader, and
gave counseling to the regular people in the cult. mr leader guy got his giant egotistical head lopped off, and bryll confessed to not believing any of that guy’s teachings so they gave wee lil grayby the benefit of the doubt
they stayed with the priests and priestesses of averus for a while, studying medical stuff and healing because despite how much they hated the cult leader, his lessons on healing were very enjoyable for bryll. the priests
wanted bryll to join them and stay as a healer permanently but that wasn’t what xe wanted; after so much time living closely with so many people, bryll just wanted to be alone.
And so, they left to find a remote place to live. after some time of travelling around, they found a marsh that seemed sufficiently offputting to keep people away. but there was a problem. bryll needed a home that was safe for
an MC to live in, and didn’t have the ability or resources to make one. nearby was a farming community inhabited mostly by humans. the masked, cloaked MC went into town and, after nearly getting the dogs called on xirself, told
them what was up. “yo i’m a healer, i need a home, i wanna live in that cool-ass swamp a few miles over yonder. if you guys build me a house i’ll totally stay away from y’all and offer healing services to anyone who shows up at
the humans told bryll to kindly gtfo with their witchy magics to which xe responded “i’m a mystical enigmatic healer just accept my offer already”
so they built a shelter, lined with some nice white-and-black wool to make the creepy demon witch go away.
and that’s where bryll spent several hundred years, living peacefully and alone, and holding up their part of the bargain. One of their favorite things to do was go diving in the deep marsh water. unfortunately, though dark and
muted, the water was tinged green and would burn bryll if they stayed under too long. the solution bryll found was to coat xirself in the thick, black, tarlike swamp mud. now protected for longer periods of time, they could dive
much deeper than before, and began discovering underwater caves.
That was cool enough in itself, but deep under the surface, something was glowing faintly. After long years of practicing dives, bryll was able to hold their breath long enough to reach the bottom and discover the flawlessly
preserved remains of humans with their hands and feet bound by lengths of rope. The glowing was from their souls, trapped in the muck for who-knows-how-long. Naturally, Bryll began making trips to retrieve and store the souls
as a reliable, though difficult, means of feeding xirself. Everything was going well, until Bryll encountered that which the humans were being sacrificed to.
On one such excursion, as Bryll began the swim to the surface with an armful of glowing orbs, they detected a presence nearby. Some ancient, edritch horror lurking deep under the water had become aware of the thief and meant to
stop them. Its body was an enormous mass of brightly colored limbs and teeth and horns, and the instant the tiny demon saw it, they dropped the orbs and began frantically swimming for the surface in a blind panic. A long, crimson
tentacle snaked up from the beast and curled around the end of bryll’s long tail, holding it for a mere second before the intensity of its color burned through completely. Numbed by adrenaline and fear, Bryll didn’t even notice
the loss. However, they did notice when that tentacle curled around their right leg at the knee. This time, it took longer. For a terrifying minute, Bryll was held in place as their leg gradually lost all feeling. Suddenly, they
were free of the creature’s grip… And one leg. By some miracle, the monster from the cave lost interest in its disabled prey.
The swim to the surface was terrifyingly slow for Bryll, who still believed the creature was pursuing. With only one leg to kick, they nearly drowned before reaching the surface. Bryll was shaking with exhaustion, lying at the
banks of the marsh. Yet, they still had to crawl back to the cabin.
After recovering, they began to wonder if it might be time to return to living nearer to the cities. However, it would be another hundred or so years before they managed the trip. The demon’s body still appeared to be young, but
their spirit had aged. Bryll no longer felt the energy they once had, and their once jet-black hair was a silvery gray. They retained the physical strength of their youth, but their mind seemed to be finished with excitement.
So, when Bryll reached the city and came across a boarding school for young demons with the same condition they had, they decided it was time to share the hundreds of years’ worth of medical and healing knowledge accumulated during their life.
