Raised in hiding, Leif eventually rose up to lead a rebellion against the southern nation of Thracia’s occupation of the northern Munster District, hoping to bring peace to the entire Thracian peninsula. Successfully liberating Thracia, Leif joined Seliph in the fight against Thracia’s ally, the Grannvale Empire. Following the war, Leif united the peninsula under his rule as first king of the New Kingdom of Thracia.
