Before entering politics, Costigan was a commodities trader. He had served as a High-Secretary 'for two administrations.' and first attempted to run for the office of Imperator in 2930, but only succeeded in 2940/2941. Since his office is bound to one ten-year limit he is not eligible for re-election.
Costigan is a Co-Iniator of the Human-Xi'an Trade Initiative (HuXa). The Jenk Gallen incident and the first deployment of the Retribution falling in his term. His term is overshadowed by the conflict with the Vanduul.
Since 2942-01-01 the UEE War Finance Committee has sold War Bonds despite the fact, that the UEE Senate hadn't formally declared war against the Vanduul. This came after a Vanduul attack against Vega II in October 2945. Vega II was also recognized under the name Aremis.
The lore about Costigan changed over time. Initially he was elected for the first time in 2928, as successor of Imperator Coley and was re-elected in 2938. In 2949 (2019), he was still Imperator. Because the office is limited to one 10-year term, the writers changed Constigan's lore.
