Abduction of Artys Arryn

The abduction of Lord Artys Arryn was an event that took place in the Third Moon of the year 200 AC that saw almost all of the main Arryn line captured by the Mountain Clans, save Creighton Arryn, heir to the Vale, and Addam Stone.

Background
Upon hearing of Artys Arryn's meager guard, and knowing his liege lord would be taking a mountain path during his return to the Eyrie, Eirik Royce sent word via coded raven message to his cousin, Donnahal Uthelhain, Griffin King of the Hill. The Royces of Runestone and the Mountain Clans of the Moon had long dreamed of reclaiming their kingship, and there would be no better chance to force concessions from the Vale than to kidnap its Lord Paramount.

Ambush
Surrounding an area of the path Lord Artys was riding down, the Clansmens revealed their great numbers to the Andals, calling on them to surrender. Realizing that there was no way out of such a trap with their meager numbers, the Lord Paramount complied, reluctantly handing himself and his family over to the Griffin King. During the confusion, Creighton Arryn and Addam Stone managed to escape to the Gates of the Moon, which was at that time held by castellan of the Eyrie Ser Benedar Arryn.

Aftermath
With the abduction of almost all of Artys' household, the Vale of Arryn was forced into negotiations with the Redsmith Confederacy on unequal footing. Initial exchanges resulted in several concessions being handed to the clans, and saw the Lord of the Eyrie safely returned to the Lowlands, though his family remains in captivity.
