In the story, Daenerys is a young woman in her early teens living in Essos. Knowing no other life than one of exile, she remains dependent on her abusive older brother, Viserys. She is forced to marry Dothraki horselord Khal Drogo in exchange for an army for Viserys, who is to return to Westeros and recapture the Iron Throne. Her brother loses the ability to control her as Daenerys finds herself adapting to life with the khalasar and emerges as strong, confident and courageous. She becomes the heir of the Targaryen dynasty after her brother's death and plans to reclaim the Iron Throne herself, seeing it as her birthright. A pregnant Daenerys loses her husband and child, but soon helps hatch three dragons from their eggs, which regard her as their mother, providing her with a tactical advantage and prestige. Over time, she struggles to maintain control of her dragons. She also acquires an army with which she conquers the cities of Yunkai, Astapor and Meereen, determined to end slavery and injustice there. Despite her strong moral compass, she is capable of dealing ruthlessly with her enemies, particularly the slave masters. After establishing herself as a powerful and relentless ruler, she sails for her homeland of Westeros, bent on reclaiming the Seven Kingdoms.
