Forthari

The Forthari are a species native to the Milky Way Galaxy.

Culture
The Forthari were one of the many races that were influenced by the Nokmadi when they visited their world millennia ago. After the Nokmadi depart they left the Forthari legends of their power gems. These legends go back a thousand cycles. And while the legends do not recall the name of the race, they say they were possessed by an ancient race who used them to see through the chaos of the universe.
