Keeper of the Gates of the Moon
Keeper of the Gates of the Moon is a title originally held by a noble charged with holding the Gates of the Moon, the winter seat of House Arryn. The post was usually granted to kinsmen of House Arryn and it was never hereditary, as the Arryns themselves had raised the Gates when they ruled as Kings of Mountain and Vale, prior to the construction of the Eyrie.
Petyr Baelish, the Lord Protector of the Eyrie and the Vale of Arryn, grants the title and the castle in perpetituity to Lord Nestor Royce and his descendants - in order to secure the support of Lord Nestor - thus forming House Royce of the Gates of the Moon.
