War of Assassins of Houses Ginaz and Moritani

This War of Assassins took place between House Ginaz and House Moritani of Grumman. The emperors of House Corrino, particularly Shaddam IV, supported House Moritani, and House Atreides supported House Ginaz.

Duncan Idaho, a Swordmaster of the Ginaz, stated that his "sword was first blooded on Grumman", indicating that his first real experience in mortal combat was part of this feud. Whether this was before or after he entered the service of House Atreides is ambiguous.
