Kel

Kel is a storm mage from Tocaiba, blessed with incredible mana reserves and poor social skills.

Background
Kel was born to two Tocaiban adventurers, and spent much of her childhood in the care of extended family and friends. Tocaiba's mana fluctuations fascinated Kel, and when storms would drive everyone else inside, Kel would do what she could to sneak out and stare up at the sky as it poured down oceans. They were a quiet child, and didn't get along well with other kids. For years, their extended family viewed her as a nice, polite young girl. But as she grew older, and didn't stop being quiet, some of that attitude turned to scorn and mockery. This was accentuated by Kel's general surliness, which led to their general lack of interest in talking to other people stop being seen as deference, and start being seen as defiance.

When they were 17, Kel's father died, and her mother, who brought the body back home, never really recovered. The family's loss of income started to send them down a spiral, until Kel decided to step up, and become an adventurer just like their parents before them. Their mother disapproved, still afraid of how Kel's father died, but Kel was old enough to ignore her and set out. Kel joined an adventuring party, acting as a scout and pathfinder, leaving the actual combat to the more senior mercenaries.

On Kel's fifth outing, they noticed telltale signs of an impending storm, and warned their party to turn back. However, her objections were overruled by the greed of her compatriots, and she sullenly joined them. However, Kel's intuition did not prove wrong, and a sudden storm took the party by surprise, forcing them into shelter. Durign the scramble, two of Kel's party members were killed, and a third one injured. That injury proved damning, as the cave they took shelter in curved downwards, and so began to fill up with water during the storm.

The alcove above the water level could only fit two people, and the partner of the injured person begged Kel to let them take it, for her to find shelter elsewhere. Thinking of her father and mother, Kel chose to let the two live with each other, and walked out into the storm herself. Kel screamed at the sky, talking to it like an old friend, pouring her heart and soul out to it, as thunder and lightning roared around her, and rain drops like bullets pummeled her.

And in a single desperate moment, Kel saw a vision, and spoke out to it, telling it that she was scared, had always been scared, and just wanted to stop being so scared. She asked for power, and Tocaiba's Worldsoul granted that wish. Kel became a half-willing vessel for a fraction of Tocaiba's power, and the storm cleared from the sky. Their eyes had become pure white, they could no longer speak, and their body felt like it was vibrating with a scarcely contained fury that threatened to rip them apart. Still, with this incredible power at her disposal, she was afraid.

Kel brought her teammates back to the city, but her new nature layered on top of her previous reputation alienated her from the rest of the village. After months of being scorned and ignored, when Kel was finally invited to join an adventuring party, she leapt at the chance. The party wanted to specifically go to a forgotten temple, only accessible during the harshest storms, and turned to Kel as a way of surviving that process. And Kel stepped up to the task, seeing the mission through, until the temple had been reached.

There, while standing on an intricate dais, one of the other adventurers stabbed Kel from behind, seeking to use their blood as an offering. Unfortunately, the only thing that poured out of Kel was pure, unstoppable mana, and the wrath of the entire world. Electricity filled the room, killing all of the other adventurers, and leaving Kel for dead. They grasped out into the distance, and dragged themselves forward, as the world shifted around them.

Their sparkwalk brought them to Zimask, one of the other planes connected to Tocaiba, directly into an emergency room. There, Kel was nursed back to health, and by the time they were released, they vowed to never trust humans again, even though they would continue to travel between the various Spindle aligned planes to engage in adventuring and mercenary work.

Capabilities
Kel is a stormmage of incredible prowess, capable of channeling vast amounts of mana to alter the weather, throw bolts of lightning, and summon torrential deluges. Kel's powers are highly augmented when she's on Tocaiba, or on one of the Spindle planes where she can leverage her connection to the worldsoul. Depending on when she is in her growth as a planeswalker, she might have more or less control over her ability to leverage subtlety with her magic. For most of her life, Kel hasn't had a lot of interest in subtlety.
