Brilliant Beginnings:

Raised in a monastery, Brilliant Purity lived a life of dedicated training. Magic, combat, clearing her mind of taint, she devoted herself to the art of combating evil. Once she was of age, she was gifted a mace that illuminated itself when close to her. She set out with nothing more than a prayer and a small celebration with dozens of other ponies.

She focused her attention on defeating evil, mostly this took on the form of driving away dangerous wildlife. Changelings, wolves, the occasional bear. The draw of combat suited her, the heat, the feeling of flesh against her hooves was thrilling. She found friends, she found purpose defeating the enemies of good. She wanted more, she wanted to be as helpful as she could and she had friends.

Targets began to change, wildlife turned into monsters. She drove herself against dark magic practitioners, horrors, and everything her world could throw at her on the surface. This culminated into a truly massive challenge, a demon.

Her party delved into a dungeon, from the first step the sheer design was nothing like the surface. Doors too tall. Scorched hoofprints throughout the entire layer, creatures not native to Equestria, the strange creature put up a fight that left her and her friends nearly dead. The dungeon would shift, every night they spent in the dungeon the rooms would shift them ever so closer to the center.

They met the demon. To call it a fight would be generous, they were immediately broken. Only one of their number didn't become a demonic plaything. Time became a joke, she cannot remember her suffering but her soul had the damage etched on to it.

Brilliant Now:

Complaint. Such a word seems to describe her. She reads her own life as a mockery for what she is now, she sees past self like a hero. It's like looking at another mare. Will she ever be that mare again? She certainly hopes so.
