The Endos Depths is a sea that sits south of the Vache Kingdom and is one of the most unpredictable places in the world. The sea is known for its turbulent waters, and it's a place where sailors must always be prepared for the unexpected. The Endos Depths is home to a vast array of sea creatures, some of which are said to be ancient beasts that have remained hidden for centuries.

One of the most terrifying creatures that sailors fear in the Endos Depths are the Leviathans. Leviathans are massive sea serpents with scales as hard as steel and teeth as sharp as blades. According to legend, they can swallow entire ships whole, and it is said to be able to control the very currents of the sea with its powerful magic. The sailors who brave the Endos Depths are some of the bravest and most skilled sailors in the world. They must navigate treacherous currents, unpredictable storms, and dangerous sea creatures, all while searching for riches and adventure. Many sailors believe that the Endos Depths is cursed, and that the sea itself is alive, seeking to swallow up any ship that dares to venture too close.

One of the greatest dangers of the Endos Depths is its underwater volcanoes. The sea is dotted with active and dormant volcanoes, and the gases and thick mists that they produce can turn a calm ocean into a highly dangerous area. Sailors must always be on the lookout for these hazards, for they can appear without warning and spell doom for any ship caught in their path. Despite its dangers, the Endos Depths is a place of wonder and mystery. It is a place where brave sailors can find riches beyond their wildest dreams, and where the secrets of the sea lie waiting to be uncovered. Those who dare to sail its waters must be prepared for anything, for the Endos Depths is a sea that can never be fully tamed.
