Once Heaven and Sylvan soldiers arrived on the island and took side with Elamon, they adapted themselves to the aquatic world, becoming Dragon’s Slayers for humans and Naiad Huntresses for the elves. Furthermore they found some monsters on the island: Mermaid and Gorgon, and in the depths of the ocean surronding them, they discovered the Mermen people with whom they developed a particular relationship, sharing fishing and fruits, developing after some time a strong friendship and becoming amphibians. But they also discovered more formidable monsters like the huge Kraken with its deadly tentacles and this creature that could never be seen coming on the surface except for defending the island : the majestic and dark Leviathan.

It is alltogehther, convinced of the importance of their mission, that they will go in crusade against the dragons.
