Put quite simply, Asana was an orphan! Whether it was by sheer abandonment of the creature or a cave incident gone wrong that forcefully severed them from their parents, they were abandoned whenever they were barely able to fend for themselves. They grew up quite quickly on their own, often relying on other animals and their habits to survive in the Underhaven. As a result of this reliance and trust built for animals, they have become quite fond of animals, aquatic or otherwise.
Asana grew older, and eventually found herself in a place of worship, and among the various rumors and/or texts towards a particular deity, she began to pray to none other than Theire. With said power, she honed what abilities she had in order to take care of wildlife and the like.
