Captain Dunn

"'I can give us one shot.'"Captain Nozomi Dunn is the captain of the human ark Hyperion.

Arrival
Captain Dunn is first encountered at the helm of ark Hyperion, navigating through an unknown energy cloud called the Scourge. She is seen argueing with Alec Ryder, the human pathfinder who suggests to follow protocol and make planetfall on Habitat 7 since there is no contact with the other arks or The Nexus. She eventually gives in to the pathfinder, remarking how stubborn he is.

After the events of Habitat 7, she leads the ark and it's inhabitants to the nexus, the control centre of The Initiative. In doing so, she was the first captain checking in with the main hub of the Initiative, as the other arks have not reported in, and are all missing.

Meridian
During the events at Meridian, the Archon has stolen the Hyperion, and with it Captain Dunn. Due to extensive dammage to the ark, it eventually starts going down. As arks were never designed for landing, Captain Dunn ordered all personel on the bridge to go to the cryo bay and rerouted power to all medbay inertials. She bravely took the helm of the crashing Hyperion, who eventually crashed on the surface of Meridian.

Fate
If Pathfinder Ryder found all arks, and found/recruited a pathfinder for every ark species, then they will help (most notably the asari pathfinder) Captain Dunn survive the crash. If one of the arks pathfinders is missing however, Captain Dunn will not survive Hyperion's crash, and her remains were commited to the stars in the Govorkam system.
