A star, often known simply as just "Drema," with four planets after an unstable fifth disintegrated into an asteroid belt circa 2215. Other planets in this system are also known to be unstable. The fourth star in this system supported a humanoid civilization.
This star often lends its name to the adjoining sector of space of five star systems overall, first visited directly by the U.S.S. Enterprise NCC-1701-D in 2365 after unmanned probes had earlier revealed unusual geological activity in all the systems.
