Oreads in Wikipedia
In Greek mythology, an Oread or Orestiad (Ὀρεάδες / Όρεστιάδες
from ὄρος, "mountain") was a type of nymph that lived in
mountains, valleys, ravines. They differ from each other
according to their dwelling: the Idae were from Mount Ida,
Peliades from Mount Pelia, etc. They were associated with
Artemis, since the goddess, when she went out hunting,
preferred mounts and rocky precipices. - Wikipedia
