Game Of Thrones: All 26 Characters From Season 1 (Who Aren’t Dead Yet) - Ranked
23. Illyrio Mopatis
Given how powerful a broker he appears in the first season - when he effectively helps sell Daenerys to Khal Drogo to cement her brother's attempt to reclaim their family's throne - it's somewhat odd that Ilyrio Mopatis simply disappeared after the season's end.
He's the kind of rich benefactor anyone looking to make a big play for power would keep by their side, but since he was complicit in turning Dany into a commodity, he might be wise to keep his head down, despite wanting her to win the Great Game.
He's not in the show a great deal, but he has significant impact, suggesting a great, conspiratorial mind to rival Varys' and an end-goal that is just as complex, given that he installs Jorah as a spy and reports back to King's Landing on her activities.
