That's pretty much an accurate description but mine is this:
- House Baratheon (MX): the ruling house of Westeros has become extinct—despite still having a king on the throne (Farmaajo).
- Lannisters (MJ): Rich and forever influential.
- Dothrakis (Hawiye): No code or morals. Their motto is to kill, pillage and rape everything that moves.
- Wildlings (Isaaq): they live north of the wall and the people of Somalia refer to them derogatorily as "wildling secessionists".
- House Frey (Dhulbahante): flip fopp floppers and backstabbers. They switch allegiances every now and then. They cannot be trusted under any circumstances.
