Biographies of main characters

[Mianna]

I know this is not important but I´m interested in what kind of bios people make for their main character.
Here´s the bio for my solo fighter/sorcerer:
"Miena is a warrior sorcerer who travels from place to place looking for adventure. She is fast, agile and very good at handeling a bow and a scimitar. She has always been interested in the goddes Selune. She has never been familiar with a clerics duty and so she turned her mind towards magical arts. She has read a lot about Selune´s clerics, the Silverblades and she holds great interest towards silver dragons as well. Staring at the night sky one day she suddenly received a task and a gift from Selune herself. She became a Moonblade, the first devoted warrior sorceror of Selune.

Miena prefers Selune as her tutor not as her god. Miena is a warmhearted young woman who prefers peace over battle. She is deadly fast in combat but every time she kills another being she feels great sadness. She is not fully shoft however and she has a very fiery soul. Once she gets angry goblins better dodge the tip of her scimitar!"
