Telmarines

In Lewis's timeline Telmar lies 'far beyond the Western Mountains.' According to the sources summarized from Prince Caspian, Calormenes once extended into Telmar and (in Lewis's account) behaved wickedly there; Aslan is said to have turned the Calormenes in Telmar into 'dumb beasts,' leaving the area effectively unpopulated. Over a century later, pirates from Earth arrived in Telmar through a rare gateway between worlds; the descendants of those pirates became the Telmarines. Many generations after their settlement of Telmar, these descendants left Telmar, invaded Narnia, and established rulership there for roughly three centuries until the events of Prince Caspian, when the rightful heir and native Narnians, aided by Aslan and awakened forces of the land, restored Narnia's former order.

Sources describe Telmarines simply as human; Lewis's text does not attribute a distinct racial or fantastical appearance to them. Film adaptations cast many high-ranking Telmarines with Spanish, Latin American, and Italian actors, but that is an adaptation choice and not a detail specified in Lewis's original narrative.

Telmarines possess no supernatural powers in the provided material; their influence is political, military, and social. Behaviorally they are depicted as conquerors and occupiers: descended from pirates who settled in Telmar, they invaded and suppressed Narnia's native inhabitants. High-ranking Telmarines in Prince Caspian are shown as politically corrupt (for example Miraz murdered his brother to claim the throne; Lords Sopespian and Glozelle plotted to kill Miraz and blame Narnians to justify war). Their rule was ended through combined political/military resistance by native Narnians and intervention by Aslan and the world's awakened forces.
