Jommo
Khal Jommo is one of the Dothraki khals present in Vaes Dothrak when Khal Drogo brings Daenerys Targaryen to the sacred city for the ceremony of the dosh khaleen. He commands his own khalasar and is accorded a seat of high honor at Drogo's table, alongside Khal Ogo, during the feast that celebrates the prophecy that Daenerys's unborn son will be the stallion who mounts the world.
Role in the Feast and the Humiliation of Viserys
At the feast in Khal Drogo's hall, Jommo is seated to Drogo's right, a position that marks him as a figure of considerable rank among the horselords. When Viserys Targaryen, drunk and furious at being denied a place on the high bench, draws a sword in the sacred city where blades are forbidden, Jommo grins broadly at the spectacle. His laughter, along with that of Khal Ogo, contributes to the public mockery that drives Viserys to his fatal confrontation with Drogo. Jommo's presence underscores the unity of the khals in Vaes Dothrak and their shared contempt for the beggar king's weakness.
Significance
Jommo's brief appearance serves to illustrate the political landscape of the Dothraki, where multiple khals coexist under the peace of the sacred city. His laughter at Viserys's disgrace reinforces the theme of the Targaryen exile's utter powerlessness among the horselords, and his presence at the high bench helps establish the context for the prophecy that will shape Daenerys's destiny.
