CTO Yu

Chief Technical Officer Yu was one of the many crew members on the Aurora. Yu and her friend Berkeley escaped the Aurora in Lifepod 2, which crashed in the Northern Blood Kelp Zone. Yu eventually met up with Second Officer Keen at the Floating Island, but Keen's final log implies she was killed by a Reaper Leviathan while attempting to board the Aurora to repair its Long Range Communication Systems.

Pre-Crash
Prior to the crash, Yu and Berkeley were testing out a new drone, although she is much more light-hearted during the matter. After Berkeley begins to berate the drone, she informs him that it's name is Albert now. The newly named Albert retrieves a Propulsion Cannon for Berkeley, and Berkeley tells Yu that she wasn't making his job any easier, or safer. Yu simply states that it's all that's stopping her from spacewalking, and adds that Alterra might buy the drone's design off her when they get home.

She also leaves message for Technician Hinkle, calling a corporate stooge, claiming that no matter the codes they install, they'll find a way to joyride the Prawn Suits, adding that if Second Officer Keen tells them that they need to change the codes, they change the codes. She then suggests a code for the robotics bay, claiming the "guys will like that".

A PDA on the Aurora states her birthday as 18.06. It is possible that this was left by Berkeley, as the two appear to be close.

Post-Crash
She and Berkeley escaped into Lifepod 2. However, she says that the flotation devices have failed, although she manages to reconfigure the O₂ system to act as a bilge pump, which in turn is successful. Yu then tells Berkeley that they have stopped sinking and are alive, but they're 500 meters down and the oxygen will run out in 30 minutes. Berkeley asks what they'll do, and she explains that they'll use the remaining energy in the Lifepod to send out a distress call and build what materials they can, and find a way to the surface.

It is assumed that Yu and Berkeley got Keen's meeting point message. However, Berkeley is not present, suggesting his demise, although Yu does not mention him. She states to Keen that they can't be the only ones that survived and they have to go back out. Keen denies, stating that Captain Hollister's orders, and were not the orders he was giving her. Yu angrily states that it wasn't chain of command; it was survival, adding that the more of them there were, the more likelihood of survival. Keen attempts to explain that it was his obligation as acting commander doesn't turn for her convenience, and asks her to get out of the water. Yu simply tells him that if she gets into trouble, she'll send him her coordinates, although Keen reluctantly follows her. Two hours later, Keen returns, and says that the rendezvous was a failure, and to consider Yu and himself lost at sea, implying that she died.

Berkeley
Yu and Berkeley have a positive relationship, and despite Yu having a higher position then Berkeley, she treats him as an equal and often teases him. It is possible that the PDA detailing her birthday was written by Berkeley.

The two manage to get into a Lifepod together, although whether this was due to convenience or they happened to be together is unknown.

Upon meeting Second Officer Keen at the Floating Island, Berkeley is not present with Yu, implying he had died or Yu was forced to abandon him.
