Giant Elementals. One of the more unusual denizens of the Elemental Plane of Water, the ikuchi can also be found in the oceans of the Material Plane, hunting the natural fauna and causing havoc for shipping lanes. Though the typical ikuchi is just under a hundred feet long, rumors abound of ikuchi that are hundreds of feet or even miles in length in the largest oceans and the depths of their home plane. Ikuchi are also known as ayakashi in various lands and are sometimes confused with sea serpents.
