|A Game of Thrones (mentioned)
Malleon was a Grand Maester of the Citadel. He wrote a book on the lineages of the Seven Kingdoms, The Lineages and Histories of the Great Houses of the Seven Kingdoms, With Descriptions of Many High Lords and Noble Ladies and Their Children.
Malleon was likely King Daeron II Targaryen's Grand Maester, because his book was over a century old, and Eddard Stark thought scarcely a man now alive had yet been born when Malleon was working on it, which suggests his time was between 100 and 120 years before Eddard's time. Moreover, Malleon's book describes the marriage of Gowen Baratheon and Tya Lannister, which occured at the end of Daeron's reign.[N 1]
