FrostNova is one of the well-known Reunion leaders. Her leadership of the famed Yeti Squadron and her frigid ice Originium Arts that could control her surrounding temperature and freeze any target earns her many titles such as the "Yeti Princess" and the "Wintry Death." In order to cast her Arts, she chants her spells in the form of folksongs and channels it through her Caster wand. However, this comes with a heavy price. She suffers from extreme hypothermia that others could get frostbite just by touching her skin. Her Arts often comes with a deteriorating health and the worsening of her Oripathy. In order to lessen her burdens, she has to share her power with the Yetis, giving them the ability to control frost and ice as well.
