Chelonith is an ancient sea beast, classified as a sea king although it is much larger than known sea kings. No one in recent centuries has seen this beast around the world; it is said to rest in the deepest depths of the New World. There are some informations in some lost books, it would seem that this creature can govern sea currents, thus generating events that can be seen everywhere in the seas: tsunamis, whirpools and knock up streams.
Legend has it that only those who come into possession of the Pearl of the abyss can control this beast as long as they can also hear its voice. It is considered a marine version of Zou.
History
Geography
This beast is a giant turtle that carries an entire island on its back. This island has been created over the centuries between sea and land, has a very high central mountain, forests as you descend, and both land and sea vegetation to surround it. It is a special island as it allows it to be inhabited out of the water and also in the water as it can be covered by a durable natural bubble generated by the shell itself, similar to the one that covers the fishman island.
