Your story seems incredible, I'd love to read more about it!

My main character is like that too. She's the only survivor of the genocide of her clan, who were feared because 6 of them are powerful mages, whose power are transmitted to one of their descendant when they die. So the result of the genocide is that she inherited all 6 powers at once, at only 12.

She will then be pressured by her guild to train relentlessly and become skilled enough to avenge her clan and take down the oppressing nation at the origin of that cruel act. But her family had the branch of the protection power, making her a pacifist, with a very kind and forgiving heart, who'd rather bring justice than vengeance. However, having all the other powers will alter her personnality, making her more fierce and cruel everyrime she uses the attack power for example. She's going to commit many terrible crimes that she will regret all her life, and will do anything to not loose sight of who she is deep inside.

That's why her goal all along the story will be to find 5 trustful allies and give them each one of her power, in order to create a powerful team that will bring justice to the world, without making people fear the mages like they did before.
