After the Nilfgaard victory at the Battle of White Orchard in Temeria during the war, he and his company occupied a ruined fort northwest of White Orchard which became their military post. He was assigned to govern the village and consequently became its head authority. He enforced fair rules such as requiring all able bodied men to help clear corpses from the recent battle.
Geralt went to meet him to seek information about Yennefer in the May of 1272. Captain Gwynleve agreed to provide the information he sought, but only if Geralt would take care of a griffin that had been causing problems in the area. This begins another quest, called "The Beast of White Orchard".
By all appearances he seemed a rather fair and kind person to the people of White Orchard, especially by the standards of most conquering Nilfgaardians. He was later seen to have a more firm attitude when dealing with local peasants who crossed him by dealing out swift punishment.
