However, now his life and throne are threatened when Eun Seom begins to gather power among the slaves and peasants of Arth as he starts to fight back against the elite. Although Ta Gon has so far kept his half-Neanthal heritage a secret from the world, his eyes shine purple, preparing to go all out in fighting Eun Seom.
