Milam Harnder is the Second Librarian in the Royal Palace of Caemlyn. He has also been Demira Eriff's spy for thirty years. He is bald and chubby (LoC, Ch. 46).
He served in the Royal Palace under Queen Mordrellen (CoT, Ch. 14).
Demira sent a message to Master Harnder to have him search the Palace library for certain books, presumably about the Seals on the Dark One's prison. She also arranged a meeting with him at the Origan Gate, but after some time it is clear for her that he did not receive the message, or else he would have shown up (LoC, Ch. 46).
Every three or four days he visits the inn Hoop and Arrow, supposedly for the good ale the innkeeper makes, but whenever he visits a pigeon is sent north. Once, three Aes Sedai of the Brown Ajah went hooded to the inn and stayed for over an hour in private talk with the innkeeper. It is not said whether Master Harnder was there as well, but he might possibly have left the innkeeper, as fellow spyn some information (CoT, Ch. 14).
Mistress Harfor informs Elayne that she found out Harnder is a spy. Because she has no false stories to feed the Brown Ajah with, Elayne simply wants to have the Librarian watched (CoT, Ch. 14).
