heskan fighter dragon born dnd background

i was only a child when war had torn my family apart. i trained my self to stay alive. And for a while things were decent. i had no money so of course being unbenouced to common people i was on my own. but i found a group of thieves. they taught that bad was good and vice versa. so i had stolen quite the stash at least enough for me to have some food and small trinkets. but one day we were caught. the thieves outcasted me. i was stuck in prison for a few days but i thought "hey i get steady amounts of food  and be warm." . days later one prisoner was kind enough to take me in he taught me my errors were bad and toughened me up he was like a father to me. he gave me a name too, heskan. a name of a fighter. the warden was cruel especially towards me and kept me locked up. but one day he executed my 'father'. heartbroken i lashed out killing the warden. i would not harm those i thought trust worthy. many cruel years later i started trying to escape but the guards caught me i lashed back and it started a prison brawl.
