Prince-Admiral/Legends
Prince-Admiral was the rank assumed by Delak Krennel as both the leader of the Ciutric Hegemony and as a former officer of the Imperial Navy once Krennel set himself up as an independent warlord.
The title itself had little real meaning and was only known to have been used by Krennel after his abandonment of the failing Galactic Empire after the Battle of Endor. The title presumably fell out of favor following his death during the second attack on Ciutric IV.
The title was also used in the Corellian system near the end of the Alsakan Conflicts. Jonash e Solo was the Prince-Admiral of Corellia during the Seventeenth Conflict, when he personally ended the conflict by forcing a peace treaty at swordpoint on the floor of the Galactic Senate chamber.[1]
