House Moritani emerged during the Battle of Corrin, when House Corrino ascended to become the first Padishah Emperor. House Moritani had fully supported the Corrino plans. Sheuset I, acknowledging the Moritani contribution to his cause, granted his Moritani allies a Viscount title and the planetary fief of Grumman. Consequently, House Moritani has remained a loyal ally of the Corrino Empire. Keshas Zhorzh was an assassin the House employed.
