Omm-wa
"It was the third year of my travels in that icy plane that I discovered what would come to be known as my greatest discovery. They lived mostly underwater, some coming to land to hunt, their language was at first a mystery to me, though soon i was able to make sense of the deep rumbling noises they made, more surprisingly, they seemed to take too common like a first language, I have yet to find a race with such an instinctual and powerful curiosity and love of learning. I am, of course, speaking of the Omm-wa" -Kel-Dor"
Omm-wa, or "Water people" as they are sometimes known, are large, intelligent relatives of the manatee. They have a natural affinity for learning and often lived in isolated tribes, until their discovery by the common world. Now the previously isolated race has adapted to trade and work with the mainland, and while they keep to their traditional ways, some decide to go adventuring into the outside world, either to defy their elders, to embark on a quest, or to satisfy the innate curiosity the Omm-wa are known for. Omm-wa society is often Matriarchal, Mothers and Male and Female Nurturers alike are given great respect, and take on leadership roles within tribes, Those Omm-wa who fight and protect the tribe can be naturally less sociable, but are fierce and steadfast combatants
