Miros X was a planet the tenth planet of the Miros star system, somewhere in the galaxy's Alpha or Beta Quadrant. A powerful narcotic drug was grown only on Miros X. This was made into cigar-like "dope sticks" and sold on other worlds. On Daros IV, an Orion drug dealer calling himself "Vasro the Dream Seller" sold this drug for 40 credits per stick. (FASA RPG module: Orion Ruse) Due to a number of errors surrounding planet names in the source, it is possible that Miros X and Miros XII were meant to be the same world.
