List of Percy Jackson and the Olympians characters
Hermes: The god of travelers, communication, and thieves. He has nearly no role in the first book but is a significant character in the second book where he helps Percy by giving him a flask full of air, backpacks, and his special multi-vitamins, hoping that he will be able to rescue his son, Luke, who had joined the Titans. He is also mentioned briefly in The Titan's Curse. He gets bitter about Luke and gets angry at Annabeth in The Last Olympian for not saving his favorite son, Luke, when she had the choice. All of his children and the undetermined half-bloods stay in Cabin #11.
