Mago is a minor character in Game of Thrones. He is played by an uncredited actor and only appears in the eighth episode of the first season. The actor playing him is unidentified.
He is a rider in Khal Drogo's khalasar.
Season 1
Mago objects to Daenerys Targaryen intervening and refusing to allow the Dothraki to take their share of the Lhazareen women as spoils of war. He refuses to recognise her authority as khaleesi and calls her a foreign whore. Khal Drogo fights him, disdainfully disarming himself and deliberately accepting an arakh wound to show contempt for Mago's combat skills before slitting his throat with his own weapon and then pulling his tongue out through the neck wound.[1]
In the books
Mago is part of Khal Drogo's khalasar, serving under Ko Jhaqo. In the books he does not die, and is presumably still alive as of the latest novel. In the novels his name is spelt as both 'Mago' and 'Maggo'.
