Grumman (second planet of the Niushe star system)

Grumman was the second planet of the Niushe star system (the third planet being the pleasure world Gamont). During the days of the Old Imperium it was the ancestral home of House Moritani.

House Moritani is principally known for its defeat of House Ginaz in a War of Assassins. House Atreides involvement in this war possibly was Duncan Idaho's first real experience in mortal combat as he stated that his "sword was first blooded on Grumman".
