Ryushusupercat/Austerine, the Blinding Surge, is a Light deity as well as a deity of the Light Clan of Celeritas.
Austerine was "born" a while after The Elemental Gods were; their powers were used to create her and her "siblings".
Afterwards, she moved from the Hyperverse to Mobius, where she went into hibernation for 100 years. Her presence, as well as the presence of Endovelicus, Malakbel, Hathor and Celeritas helped to keep the Elemental Plane of Light stable and balanced with the other nine Elemental Planes.
Austerine commands both Solaramancy and Fulguramancy. This also allows her to use the Advanced element of Laser.
