The Dream-rock
Dream-rock, situated within the Dark Heart region of the Nightmare Lands on the planet Voss, was a distinctive type of rock. This rock held the very essence of a Voss Mystic named Dal-Rin and played a role in the Forbidden Ritual. In this ritual, a Gormak was required to utilize the dream-rock. By doing so, they could transform a participant's nightmares into a physical form, making them able to be defeated. Around the year 3640 BBY, the Sith Lord Kallig, along with a Gormak known as Hadrik, employed the dream-rock and conducted the ritual. This allowed Kallig to effectively silence the Force ghosts of Darth Andru, Ergast, Kalatosh Zavros, and Horak-mul that were present within their mind.
