Krakens

Krakens are gigantic squid-like beasts that live in deep waters.

Livyataan

This being dwells within Kva tan Dosvek. It stalks the depths and eats ships that sail too far from the shore.

Others

The humans know of other krakens that inhabit the open oceans. They rarely target ships and also often sleep for months after eating, so they are not nearly as feared as the Livyataan.
