Forfra moss was a pungent moss that grew on the ceilings of underground caverns on the planet Almas, located in the Cularin system of the Expansion Region. The moss was slow-growing and was eaten by the legendary k'kayeh dragon, a creature created by the Sith Lord Darth Rivan. As the moss was toxic to the k'kayeh dragon during some parts of its development cycle, the creature waited to eat it until its smell was unmistakable.
