Starting Rank: 7
The Greyjoys have few resources at their disposal, and their raiding culture makes prospects for economic advancement unlikely at the start of the series. A lack of rich forests makes building ships difficult.
By the end, the Greyjoy financial picture has clearly improved, but the details are fuzzy. Euron Greyjoy’s pledge to build 1,000 ships at the end of Season 6 is clearly hyperbole, according to military experts. Still, boats are valuable, particularly when used for such things as trading rather than raiding, and the growth of this fleet indicates a rise in the ruling family’s fortune.
House Martell
Current Rank: 6
Starting Rank: 6
The sandy region of Dorne is limited in population and in arable land. Exports include wine and grapes. House Martell does have a fighting force and some ships, although the story provides few details about their number.
Though most of the main characters in this house are dead by the end of Season 7, it likely still exists in some form; Oberyn says in Season 4 that he has eight daughters. Meanwhile, Dorne’s isolated locale would have insulated it from excessive material damage.
House Tully
Current Rank: 7
