Ironclaws, 1011 y.a.b.; Left to right: Darius II, Alex I, Rhosus II, Cassandra I
In the northern regions of Griffonia, clans of griffons eke out a tough existence amongst the frigid crags, far removed from their more peaceful relatives to the south of the continent. Here the right to the throne belongs to the House which proves themselves most powerful, and matters of succession are often unsavory affairs.
The late King Gryphus III of House Ironclaw rose to power as a popular figure but grew increasingly megalomaniacal in his later years, seeking to expand his rule by establishing a vast empire. Gryphus looked to magical artifacts as a means to fulfill his ambitions and in 1006 y.a.b. he invaded eastern Equestria, sweeping through the kingdom towards its capital. He was defeated in the single day Siege of Canterlot.
Gryphus' younger brother Rhosus claimed the throne after his death. Gryphus was also survived by his three children (eldest to youngest): Darius, Cassandra, and Alex.
The capital city of North Griffonia is Twistspire.
