With the entire Brísingr Cluster under Windermerean control, the Macross Elysion and Ragna's surviving citizens become space refugees as the Island's life support systems are on the brink of failure and Chaos is low on armament and funds to stage another attack. A breach in the Island's hull causes a loss of gravity that separates Freyja from Hayate and Mirage in the underground corridors. Freyja regroups with Walküre to calm the civilians while Hayate and Mirage race against time to get the Island's power supply back online.
