Jonos Arryn

Jonos Arryn’s brief seizure of the Vale turned a family coup into a challenge to royal authority: after imprisoning his brother Ronnel, he claimed the title King of Mountain and Vale, but his rule collapsed under the threat of Balerion. His end mirrored the fate he had imposed on his brother, making the Moon Gate the instrument of both the coup and its reversal.

Seizure of the Vale

While King Aenys was confronting a wave of rebellions elsewhere, Jonos deposed and imprisoned his loyal elder brother, Lord Ronnel Arryn, and declared himself King of Mountain and Vale. The claim asserted independence from the ordinary order of rule, but the evidence records no wider basis for Jonos’s authority beyond his seizure of the Eyrie and his self-proclaimed title.

Jonos’s coup also made the Vale’s rebellion a crisis of succession within House Arryn. Ronnel had previously flown three times around the Giant’s Lance on dragonback; now his brother held him captive while presenting himself as king. The contrast between Ronnel’s established lordship and Jonos’s abrupt claim sharpened the conflict over who was entitled to rule.

The Eyrie and the Moon Gate

Lord Allard Royce of Runestone gathered forty loyal bannermen and marched against the Eyrie. They defeated the supporters of Jonos’s claim and demanded that Ronnel be released. Jonos instead sent his brother through the Moon Gate, killing the rightful lord rather than surrendering him to the loyalists.

The Eyrie could not be taken by a conventional assault, and Jonos and his remaining followers initially resisted from within. The balance shifted when Maegor appeared above the castle on Balerion, the Black Dread. Faced with the dragon’s threat, the garrison seized Jonos and handed him over to Lord Royce; the defenders opened the Moon Gate again, and Jonos was put to death there, in the manner he had chosen for Ronnel.

Aftermath and Significance

Jonos’s rebellion ended with the Vale returned to Arryn rule under Hubert Arryn, a cousin of the dead brothers. Hubert already had six sons, and his marriage to a Royce of Runestone helped make the succession appear secure. The account thus closes not only with Jonos’s removal but with the installation of a replacement whose heirs and alliances promised greater stability.

Jonos’s rise and fall turn the Moon Gate into a stark measure of political reversal: he used it to eliminate the brother whose place he had taken, then lost his own rule when force brought the Eyrie to surrender. His self-styled kingship lasted only until a dragon made resistance untenable, showing how quickly a claim made through seizure could be undone by the greater power of the crown.
