Arc 6The Lost Frequency
Mo Bai fought Phrolova and Leviathan while helping Rover search for her lost frequency. The search uncovered Rover’s connection to Aemeath and Singulum, and Aemeath began revealing their shared past as she prepared to face Singulum with Rover.
- Mo Bai trapped Leviathan in his shadow domain, killed the Threnodian offshoot, and fought Phrolova, who eventually withdrew when Rover arrived.
- Mo Bai told Rover that the Remnant Star Society had tried to make him a Threnodian Resonator, and Rover agreed to trust him if he stayed by her in the field.
- Mo Bai, Rover, and their companions explored a crashed space station, where a recording showed Rover falling from the Sky Sea before the group defeated its infected Pioneer.
- Lu Hess revealed that Rover led the Black Shores, destroyed the recording, and asked Mo Bai to keep Rover safe.
- Mo Bai and Aemeath fought Singulum together, and Rover discovered they had hidden their connection and that Singulum sought her frequency and authority over the Tunneler.
- Singulum attacked near an Ornamental Lake, where Void Matter reached for Rover and she collapsed after losing too much frequency.
- Rover watched lingering recordings of her childhood with Aemeath, who explained that they had lived together after Aemeath lost her parents to the Threnodians.
- Aemeath described her life at the Academy and as a Digital Ghost, promised to help Rover defeat Singulum and recover, then left after Rover fell asleep.
