|“||He's so goatly.||”|
–Mellie talking about Gleeson Hedge
Mellie first appears when Jason Grace, Leo Valdez, Piper McLean, and Coach Hedge arrive at Aeolus's floating palace, and introduces herself as his personal assistant. Mellie seems offended when Jason asks if she was a ghost, but the problem was solved by Piper as she says Jason mistook her for Helen of Troy, and Mellie seems to blush. She shows signs of liking Coach Hedge, but continues to escort them to Aeolus and floats over a large hole in the floor as she forgot that the group couldn't fly. When Aeolus says that Jason was here last year, Jason asks Mellie for confirmation. She does not know however, as she was only hired about twelve hours ago, but was still working there longer than most.
When Aeolus received an order from an unknown being to kill the group, he apologized and tried to kill them. Mellie had stepped in, however, allowing them to escape, thus resulting in her being fired by Aeolus. Now she works for Piper's father Tristan as his personal assistant and is in a relationship with Coach Hedge.
Mellie is petite and has dark slowly flowing hair, brown eyes, with pointed ears, and a timeless face. She carries a white iPad type device, wears a white dress, and is said to be ghost-like due to being partly transparent.
- Aerokinesis - As an aura, Mellie can control and therefore manipulate the air and wind like she does in The Lost Hero.
- Nymphs mostly tend not to like satyrs, but Mellie, like Juniper, is an exception.
- She was thought to be a ghost by Jason Grace on their first meeting, a common mistake made by people that see wind nymphs.
- Aurai (or anybody for that matter) don't last long as Aeolus' assistants; however, Mellie lasted longer than most, at around twelve hours.
