List of characters in the Camp Half-Blood series
Aeolus - The custodian of the Four Winds. They never made an appearance, but they were mentioned in The Last Olympian. They made it hard for the Titan army to hit Olympus by air. Consequently, it also made it harder for Pegasi to fly. In "The Lost Hero," Aeolus is shown to have gone crazy filling out the gods' weather requests and wants Zeus to make him a god.
