Keara warns of marshmen migration

As the TARDIS crew regroups following a rough landing, tension spikes between Outlers and Deciders. Keara interrupts the squabbling with a grim observation: when the planet’s Mists surge, the giants abandon the swamps, foreshadowing the arrival of the amphibious marshmen. This revelation shreds the last veneer of control, exposing how swiftly the planet’s threats can reshape power dynamics. The crew’s choice to investigate the scanner’s failures confronts them with an immediate, visceral danger none can ignore.
