Oswald was born into a blacksmith family and raised to use tools to make weapons and armour, however he longed for a chance to serve in the military of the Kaiser Jorynn Giantslayer. His father forbade him from doing so, but later he was killed in a massacre of Oswald's Village, Gustenalle, by Giants from the northern lands of Lorz and led by their King Vandul. Oswald swore vengeance for his father and for 13 years he worked his way up the military to eventually become a Captain. Using his influence Oswald led a band of 700 men to battle the Giants in their Fortress of Gornazir(Iron Mountain). During the battle Vandul was hit by a stray arrow in his gut and Oswald's best friend, Uther, was cut by a poisoned blade resulting in Oswald going berserk and charging the last few Giants. After the battle was over Oswald was found dead surrounded by several Giants bodies. He was buried and in his name, Kaiser Jorygg named the most fearsome warriors of his army Bunderseigen.
