In the Homecoming Wings arc, Zayne joins the medical team treating Kevi and Mia, two children injured in the Bloomshore District explosion. MC meets Zayne at a Skyhaven hospital with Mia. Kevi is the more critical case: he possesses an Aether Core Shard, and his deceased parents warned him to keep it away from the Farspace Fleet — Caleb's current organisation. Kevi is growing black crystal shards that are identical to those Zayne carries and to those from the Chansia and N109 incidents. Zayne and MC arrange to transfer Kevi to Akso Hospital for treatment. The arc also takes Zayne and MC to the Arctic to visit Dr. Noah — the former Chief Medical Officer of Akso, MC's original cardiologist, and the doctor connected to Mt. Eternal. This is the Homecoming Wings visit that resolves the Mt. Eternal backstory thread.
