Ado Di was a Force-sensitive human male, who served in the Galactic Empire as a Commodore in imperial special forces. Hailing from the upper echelons of Coruscant, he was arguably one of the most famous and highly decorated graduate of the Royal Imperial Academy.
Ado Di graduated from the academy faster than anyone in the academy history; by 10 BBY he achieved the rank of captain by the age of twenty, attaining the rank faster than any other person in imperial history, which made him something of a legend as well as a target for some imperial officers, who did not like his swift rise to prominence.
In 10 BBY, he attained captaincy of an Arquitens-class command cruiser called the ????? and was assigned to Imperial Special Forces, completing sensitive missions primarily in the Mid Rim and Outer Rim Territories. In 5 BBY he was given the command of an Imperial II-class Star Destroyer called ????? and was stationed exclusively in the Outer Rim Territories.
In 0 BBY, he took part in the last half of the Battle of Scarif, with his ship arriving a few minutes after Darth Vader’s flag ship. After the Darth Vader and Grand Moff Wilhuff Tarkin left Scarif, Ado Di was left in command of all remaining imperial forces in the system. Several weeks later he was promoted to commodore and acquired his personal flagship ??????.
