Classes of Nymphs

['HERA]

There are many classes of nymphs.

Although there many classes of nymphs, it doesn't affect if your nymph character (who is a spring nymph) isn't able to go to the sea or lakes, if she's a dryad, it doesn't means she can't go anywhere except staying in their trees.

They're called nymphs, after all, which makes them able to go anywhere they like.

• ANTHOUSAI
  Nymphs of flowers. They were probably the same as the Leimenides, a type of Okeanis.
  
  
• AURAI
  The nymphs of the cooling breezes. They were daughters of the wind-god Boreas, or Okeanos, the earth-encircling fresh-water stream.
  
  
• BAKKHAI
  The Bacchic nymphs, companions of Dionysos. They were also known as Thyiades.
  
  
• DRYADES
  The nymphs of trees and forests. Some of them had their life force bound to that of a specific tree, usually the loftiest in a forest, or one in a sacred grove of the gods. Dryades of mountain pines were known as Oreiades, those of ash-trees were called Meliai, Hamadryades were of the oaks, and Meliades of fruit-trees.
  
  
• ELEIONOMAI
  Naiad nymphs of fresh-water marshes.
  
  
• EPIMELIDES/MELIADES
  (or Epimeliades) Nymphs of highland pasture, the protectresses of sheep-flocks. They were perhaps numbered amongst the Okeanides.
  
  
• HALIAI
  Nymphs of the sea, the sands, and the rocky shores. They had the schools of fish, and other sea creatures in their keeping. The most famous of them were the fifty Nereides.
  
  
• HAMADRYADES
  Oak-tree Dryades whose life force was bound to that of a particular tree.

  Torch-bearing nymphs of the underworld. They probably belonged to the train of the goddesses of the Eleusinian Mysteries, Persephone and Hekate.

  Nymphs of honey, bees and honeydew (manna). They were also Dryades of the mountain ash.
