Aquis is the Sliver of Water, controlling the movement of water through the atmosphere, as well as reflecting water's association with empathy and medicine. All Inanimae who know Aquis are capable of breathing underwater, and automatically know how to swim. Aquis is primarily practiced by the Ondines, but the Glomes and Kuberas also have affinity for it.
