Oldest issue of Martin V.  Born in 401, proclaimed empress by the Moot in 457, murdered in 475 by Cleon IV.

Eleventh in the line of emperors of the Imperium.  Second empress to hold the throne.

The fact that Nicholle was assasinated by her successor is indicative of the strained fabric of the Imperium in those days before the Civil War and the Barracks Emperors. The incident, and the pressure of certain member worlds of the Imperium led to the establishment (now somewhat discredited) of succession by right of assassination.
