Fortuna is the Demon Stone of the Vision Clan.
She appears as a naked woman, with three sets of eyes and long hair. When she starts using her power her normal eyes close and the upper pairs open so that she can see possible futures.
Being an other dimension deity, she is quite mysterious and only contacts chao's residents who have proven themselves worthy of handling her powers. But she is quite protective of those who she finds worthy, and develops a maternal nature towards these individuals. She reprimands Heklaroth for overusing his vision powers to have a glimpse into Caladborg's plans.
