Aggo
A Dothraki archer of Daenerys's khas, one of the three young riders who remain sworn to her after the khalasar scatters.
The fuller tale
Aggo is the bowman of the khaleesi’s khas — one of the young Dothraki warriors assigned to guard Daenerys in her days as Drogo’s bride, and one of the few who remain when the khalasar’s dissolution strips her retinue to a handful. The books make him the best archer in her service, his double-curved dragonbone bow a small legend of its own, and give him the dry, scandalized piety of a rider raised strictly in the old ways: it is Aggo who mutters that this or that business is not done, even as he follows his khaleesi into every one of the not-done things her story consists of.
With Jhogo and Rakharo he forms the trio Daenerys raises to ko and calls, over their own embarrassed objections, as good as bloodriders — the custom having no category for men sworn to a khaleesi. The books keep him busy at exactly the errands such men exist for: scouting the red waste, riding escort through hostile cities, commanding her Dothraki in the field at Meereen, and executing the queen’s justice when it needs a rider’s speed. He is not a large character and is not meant to be; he is the institution of the khalasar, rebuilt in miniature around a queen, and his steady presence in the books is one of the quiet proofs that her claim on the Dothraki was never only Drogo’s ghost.
The page and the screen
Aggo barely exists on screen: the show folded most of the khas into a couple of faces, spent Rakharo for shock and invented Kovarro to replace him, and Aggo’s name attaches only to a fleeting first-season presence most viewers never registered. In the books he is alive and consequential to the end of the published run — one of the queen’s kos in Meereen, still at her side through A Dance with Dragons — and readers of the later chapters will find him among the riders whose loyalty survives even her disappearance into the Dothraki sea. The show’s Dothraki became a mass noun; Aggo is one of the names the books kept individual.
