Harpy

The Harpy (Ancient Greek: ἅρπυια/harpyia) is a monster seen in Age of Mythology. They are female avian creatures with the face of a woman and green plumage, who live exclusively in the Greek Underworld, Hades' realm.

Overeview
They are flying, unselectable units that cannot be attacked, yet can be killed, mainly by the Son of Osiris' lightning attacks and Zeus' Lightning Storm. Essentially, they replace Vultures and Hawks as decorative "birds", as they are completely harmless, despite looking monstrous.

If a Harpy, is killed, she will fall straight to the ground. Harpies produce no sound, other than the beating of their wings.

Appearences
Harpies appear exclusively in two maps: River Styx and Erebus, both in the Greek Underworld. Apart from that, they make their appearence in Fall of the Trident scenarios that feature the Underworld, such as Strangers.

Trivia

 * While Harpies are harmless in-game, in Greek mythology they were fierce creatures, known for carrying evildoers to the Furies, in order to be punished.
 * Harpies were planned to be featured for the Greeks, along with other creatures and units, such as the Griffon.
