House Mudd

"House Mudd once ruled as Kings of the Rivers and Hills. But after a thousand years their line was exhausted and fell to the Storm Kings, who fell to the ironborn."

- Ser Brynden Tully

House Mudd is an extinct noble house that once ruled the Riverlands as Kings of the Rivers and Hills. Eventually, however, their line was seemingly extinguished after being defeated by the Durrendon Storm Kings.

In the books
In the A Song of Ice and Fire novels, House Mudd was the last dynasty of First Men that ruled the Riverlands. Their seat was a castle now in ruins and called Oldstones. Under King Tristifer IV, "the Hammer of Justice", they resisted the Andal Invasion. Tristifer IV was said to have been victorious in ninety nine battles, but was defeated at his hundreth, in which seven Kings banded against him. Under his successor, King Tristifer V, House Mudd fell to the Storm Kings.

In Essos there are still Westerosi exiles with the surname Mudd, but it is unknown if these are true descendants of House Mudd.
