Golmar grew up the 4th of 7 children on a farm. He was large for his age, and was a great help to his family. He even enjoyed doing farm work. As he grew older, he became aware of his parents' struggles, as they worried about being able to feed the family over the winter while paying the local lord's tithes.
He came to despise these faceless lords that demanded a tenth of the crop, giving them nothing in return so far as he could see. Then he started noticing other things. Men in mail wielding swords, who would stay with them for an evening on their way to some grand tourney, or towards whomever needed a body for their army. His heart yearned for a life of adventure and, secretly, he yearned to not live year to year in fear of starvation under the thumb of a petty lord.
He bid his parents and siblings farewell when he came of age and traveled to the nearby city, where his size and muscle quickly found him a job as hired muscle. Three years later he is a competent sellsword, recently having completed a job and looking for work.
