An advisor, or adviser, was an individual who helped another individual—often a a leader, such as a King or Emperor—make decisions. On the planet Mon Cala, Mon Calamari Captain Gial Ackbar served as a military advisor to King Yos Kolina during the Clone Wars. Galactic Emperor Sheev Palpatine employed several bureaucrats throughout his reign that advised him on how to rule his galaxy-wide Empire. Approximately four years after the Battle of Yavin, Gallius Rax proclaimed himself Counselor to the Empire, an unprecedented title tasked to act as an adviser to the shattered Empire.
