Believers

The Believers were a Sith cult that practiced the dark side of the Force on the planet Cularin, and was initially dismissed as a rumor by the Jedi Knights. The cult became a very dangerous threat to the Jedi who saw many of their number joining the Believers during the Clone Wars. Eventually it was discovered that the cultists were using the ancient Almas Sith fortress as their base of operations. They had also spread to the ruins of the Almas Academy after its destruction. All Believers could be recognized by a distinctive tattoo, which resembled the spire of the Sith fortress on Almas with a broken lightsaber at its base.
