Gaven was born and raised as the youngest son of the noble Deverin family in Magnimar. He was bullied often as a child from other noble children, who liked to call him 'the simpleton'. His older brother, Wade, would always step in and protect Gaven, even if Wade got in trouble for it. In adolescence, the two worked at the family's brewery, the Fancy Reefclaw, to raise money for martial training. Their tutor was an old paladin of Abadar, and in addition to learning how to fight, both Wade and Gaven picked up the faith.
Their knighthood didn't last very long before the two decided that adventuring wasn't quite for them. They felt like the Magnimar guard was better equipped within the city, and neither brother was keen on delving into the wilderness of Varisia. Still the best of friends, they decided to move to Sandpoint where their cousin Kendra lives, and opened a brewery called the Two-Knight Brewery. It was quite successful for a few years before Wade was suddenly murdered by the Chopper, and sacrificed to a demon lord. This completely broke Gaven. Five years later, he still hasn't recovered from the loss of his brother and best friend. The brewery slowly went under while in his grief, and he was forced to sell it to Titus Scarnetti. Out of her heart to help Gaven, his cousin Kendra asked him if he could go help Keleri, his sister with some important task. With the little money he has left, he agreed and bought a ride back to Magnimar, where he hopes a change in scenery will improve his spirits.
