In 2374, Dawn altered the course of the USS Phoenix-X during its first ultra-transwarp test-run: bringing them to Professor Gast's Planet. But while on the planet, the Captain was able to over-power attempts at taking control of him, and both Gast and Dawn were placed into the Phoenix-X`s brig. After being captured, Dawn was incarcerated by the Federation.
A few decades earlier, Dawn put all his effort into overthrowing the Umockian Empire. He claimed that it was to prove to his mother that he wasn't a failure.
- It has not been said how long Dawn was in Starfleet before 2374. He may have passed Starfleet Academy, or he may have simply found a way to pass as a Starfleet officer long enough to hijack the Phoenix-X.
- It is also uncertain how he was able to take over the Umockian Empire.
