Krun Macula
Krun is the westernmost of the "Brass Knuckles", a series of equatorial dark regions on Pluto. It is named after Krun, the greatest of the five Mandaean lords of the underworld.
Krun is the third largest equatorial dark region on Pluto, after Cthulhu and Balrog. It extends nearly to 180 degrees longitude, the Plutonian longitude opposite Charon.
