Callisto, a Phin Singer, is the current matriarch of her pod. She is considered the wisest of the group and has taken over from there. She is a gentle soul who enjoys the natural world. She loves to race the youngsters and often is the source of guidance and counceling for the pod. Her pod consists of other Phin Singers. It is rare to see another speices of Aqrion in the pod, but it's not unheard of. Cappuccino is, currently, the only Aqrion who isn't a Phin Singer in the entire pod. He was adopted by Callisto and she considers him as family. She and him are nearly inseperable and are rarely out of echolocation range for eachother. She is like a mother to most of the pod and is considered as such. She enjoys using her element to amuse the youngsters and to keep them out of their parent's fins, especially during hunts.
