Umi-Bozu's Teeth was the name given to a vast whirlpool found in the center of the archipelago Eternal Danger Islands. It destroyed any kobune which dared to sail on it. The whirpool's name was taken from Umi-Bozu, the terrible sea-trolls who some ships' captains claimed to have seen. [1] The Kuni belived the maelstrom concealed a portal to Jigoku, but the Phoenix claimed the presence of Tainted creatures was due to spiritual imbalances. [2]
