Drema IV

Fourth planet of the Selcundi Drema system, home of a humanoid race unaware of interstellar travel and, like the other worlds in its sector, plagued by volcanic instability. It was found to have the largest deposit of raw dilithium ever discovered, which was believed to be the cause of its instability prior to the intervention of the U.S.S. Enterprise NCC-1701-D, which helped relieve the tectonic pressures and, in the process, save the planet’s native people without their knowledge.^[1]
