Season 1

The age of gods is dying, and the tribes of Britain descend into chaos. One man hears a voice that will change history.

A forbidden union gives birth to a prophecy that will outlive the world that made it.

Hardened by exile, Merlin returns as old powers fall and the Saecsens rise — his visions more urgent than ever.

A Britain bleeds, Merlin must forge unity from chaos — while darkness moves behind kings and blades.
