Dromund Kaas lichen

This species of lichen grew on the planet of Dromund Kaas in the Dromund system. It thrived in gloomy conditions, growing on stone and it gave off a faint purple glow. During the time period in which the reconstituted Sith Empire held Dromund Kaas as its capital the lichen was considered rare. At this time, Darth Nyriss, a Human female Sith Lord and member of the Dark Council, used the lichen to decorate the courtyard of her stronghold, where it was planted in decorative patterns amongst white stone pebbles. The Sith Lord Darth Scourge noted the lichens presence when he was summoned to the stronghold by Nyriss in 3956 BBY to investigate attempts on her life.
