A Feast for Crows (mentioned)
Walgrave was considered by many to have the foremost knowledge in ravencraft, and wrote a book about the subject called Black Wings, Swift Words. His chambers are located in the west tower of the Ravenry, below the rookery of the white ravens. The white ravens are Walgrave's pride, and he wants them to eat him when he dies.
Walgrave once taught Maester Yandel how to read. However, he is now an old man and keeps the title archmaester only by courtesy, his wits having left him a long time ago. He often soils his smallclothes, and has been found weeping in the Citadel's Library, unable to remember the way back to his chambers. The novice Pate has been assigned to help him, tending the ravens, fetching Walgrave's meals, cleaning his chambers, and dressing him every morning. Walgrave cannot recall names very well (though he can easily tell one raven from another), and often calls Pate by the name of Cressen. Maester Gormon now judges those seeking a black iron link in Walgrave's place.
There is a strongbox underneath Walgrave's bed, containing a bag of silver stags, a lock of yellow hair tied up in a ribbon, a painted miniature of a woman who resembles Walgrave (even to her mustache), and a lobstered steel knight's gauntlet that supposedly once belonged to a prince. The box also contains Walgrave's archmaester's key, which can open any door in the Citadel. The strongbox's lock was broken by Walgrave after he lost the key that opened it.
A Feast for Crows
Maester Walys was the bastard son of a Hightower girl and an Archmaester of the Citadel. Because of the personal items in Walgrave's strongbox, and the similarity of Walgrave's and Walys's names, some suspect he was the Archmaester who fathered Walys.
