Zasha Ranken was already a rising Imperial star when Grand Moff Kilran handpicked her to serve under him during the Great Galactic War. Ranken's steely resolve and unwavering loyalty made her a vital component of Kilran's campaigns. During the historic Sacking of Coruscant, it was Ranken who coolly recommended the bombing of civilian population centers that would earn her mentor the nickname of “the Butcher of Coruscant”.
Now, as the celebrated admiral in command of the Imperial Forward Command, Ranken has adopted her mentor's affinity for bold initiatives, taking great pride in her capacity for cold and rational decision making. Ranken is always willing to listen to reason, even if it means allowing a contradictory voice to be heard, but she does not suffer circuitous talk or outright insubordination, opting to teach those who cannot or will not learn to be direct and respectful the error of their ways.
