During the Storm of Ages, a few hundred humans lost their lives while they were traveling on cargo ships that was heading to a new town that was being built. A Whale God found these humans and felt sad for them. So he resurected them but for them to return to the surface, they would have to remain under water until their God would return. They were given the ability to create the same sounds as their god, whale language, and their ears were modified to undestand it. They were also given under water pets, who could transform into unbreakable weapon or change into an unbreakable shield armor. (but they cannot be both at the same time) It was centureis before their god returned and gave them permission to walk the surface, but by then none of the orginal humans were still alive, but at least their legacy lived on.
