Kueller, an army general from Almania, existed centuries prior to the Almanian Uprising. He successfully overtook Almania, subsequently gaining control of the complete Almanian sector. Although he was a ruthless conqueror in his early days, willing to use any means necessary to solidify his authority, he became a cherished leader later in life, recognized for both his empathy and his strong decision-making abilities.
In the year 17 ABY, the Dark Jedi named Dolph adopted the moniker "Kueller," aiming to emulate the historical general.
