Water Elementalism
Water elementalism is the form of Elementalism native to the Mariel due to their spiritual bond with the elemental water spirit Undine. This ability allows for the manipulation of water in and out of their aquatic environment.
The ability to manipulate water comes natually to the Mariel and all individuals are capable of it, to varying degrees. True mastery requires devotion and practice, including meditative practices that allow Mariel to commune with the Undine spirit bound to their souls. Half-Mariel born to a Mariel mother inherit their ability from her, though their potential may be limited if mixed with human blood or an opposing element (Fire or Light).
Basic skills for Mariel include the manipulation of currents to push, pull, and improve their movement in the water. During their brief period on land, Mariel are still able to use their elementalism even though the environment is different from the one they are accustomed too.
