The Grumani were orthodox adherents to the Children of Mani religion.
The Grumani split from the breakaway Spumani in a relgious schism, resulting in a conflict that was fought between the two sects for eight hundred years, until the arrival of the Sith in the Grumani sector during the New Sith Wars. Tenisons between the two groups later cooled to merely mutual disdain.
