Miraud was a planet located somewhere in the space of the galaxy's Alpha or Beta Quadrants, at the boundaries of Klingon Empire space.
History and specifics
Miraud had a science outpost, considered useless and insignificant by some Klingons. Science Outpost Miraud was reputed to be manned by broken veterans, misfits and pacifists.
In the year 2286, Miraud's outpost came under attack by Captain Zair and the "renegade" starship USS Zephyr. The outpost and all but one of it's personnel, a simple-minded diminutive albino named "moron", were killed in the bombardment by Zair's mercenary crew.
