The son of Ankiseth Gallant, Magnus originally served as an officer in the southern division of the Palatinean army. Later, he defects and joins the rebellion, forming his own battalion: the Blue Knights.

At a young age, he witnessed his father kill a noble who intended to assassinate his childhood friend, Prince Yumil Dulmare. The people called Ankiseth a murderer, and he never denied it, which pushed Magnus away from his father. At the age of 12, he left Latium to join the Military Academy. Upon graduation at the age of 18, he was assigned to the Southern Division under General Godeslas.
