Alcyona

Alcyona is a giant monster and one of the six sages the Ancient Ones created to guard the Keystones. Alcyona resides is the Boiling Bay, where one can also find the shrine of the Water Keystone. Alcyona has rarely been faced by anyone, as it doesn't come to the surface often, and if one would attempt to defeat this monster, he would have to do so in the boiling waters of the bay, where Alcyona has the advantage. Alcyona takes the form of a large three-headed sea-serpent with razor sharp fangs. It's scales are hard and invulnerable to most attacks.
