Lady Lucy the Night Caster
"Lady Lucy the Night Caster once wielded the power of light. However, during a great battle, Lucy was bitten by a Titan of the night. Tried as she did, there was nothing she could do to stop its venom from coursing through her veins and soon even her powerful light magic was transformed by the darkness.
Terrified by this change, she fled her home leaving behind her family and her beloved sister. She knew that she could not bring herself to face them now that she belonged to the darkness. Her magic no longer healed and protected, but wreaked havoc and brought desolation. It felt as if everything that her family once stood for - light, justice, hope - was now ruined because of her.
For a long time, Lucy hid high up in the mountains, frantically trying to bring her newly dark magic back to the light. She hated herself. What she allowed to happen to her was unforgivable. Lucy fell into despair. Her only comfort was the tireless training she put herself through every day. Even though Lucy was now a night caster, she vowed to not stop practicing until she found a way to use her magic for good. She would use this magic to protect others from suffering, instead of bringing it upon them. They would call her Queen of the Night and she would use the dark forbidden magic that she once feared to stop the true evils of the world."
