Author: Kyria d'Oreyn
She has to share a room with Moiraine in The Gates of Heaven, because the innkeeper made sure the three Aes Sedai that were staying at his inn would have enough space for themselves. After entering the room that was formerly Moiraine's alone, she begins placing her things everywhere and removes Moiraine's, because she believes that Moiraine will be going to the White Tower as novice. Once Moiraine returns, Mistress Palan talks incessantly, lecturing her on the duties of a novice, although her information is not reliable at all.
She has cold feet, an unsettled sleep and she snores.
(Reference: New Spring, Chapter 18)
"She lectured Moiraine on the duties of a novice, all of her information wrong. Some of what she suggested would have killed most of the novices in a week if not on the first day, and the rest was just impossible. Learn to fly? The woman was mad! She followed Moiraine down to supper and gathered other traders of her acquaintance at the table, every woman of them eager to share what she knew of the White Tower. Which was nothing at all. They shared it in great detail, though." (Moiraine about Mistress Palan; New Spring, Chapter 18)
