Yif is Go-Back who lived during Kahvi’s reign. He wielded a troll-forged sword and fought in the First War for the Palace against King Guttlekraw’s troll army. He was among the Go-Backs that showed Skywise that his people weren’t just mean and cold during the dance before the war. He was mortally wounded during the final battle and died atop the pile of warriors who died in the glory of battle.
