Mils Giel was a lieutenant in the Imperial Navy. With relatives who had been serving Emperor Palpatine since 19 BBY, Giel became an admiral in the Navy, and personally oversaw the creation of the largest armada in Imperial history. He was called upon by Palpatine to transport a rare teezl—a giant life-form capable of transmitting electronic information at the speed of thought—to Imperial Center. While in transit, his flagship was attacked by Alliance pilots, and the teezl was destroyed.
