Naiads

Naiads or River Nymphs were the gods and goddesses who lived in rivers and streams. They were most commonly found in the Great River of Narnia. They were human-like in appearance but had hair that flowed like water and crowned with rushes, skin in shades of blue, grey, and green. There were male naiads as well as their father and chief the River god, who had a weedy beard. The River Nymphs were usually seen with a dryad or two and have a black dress and dark bluish-green hair that falls down to their shoulders and the bottom edges are shaped like fins or spikes. They carried Queen Helen's train at her coronation. The were awoken by Aslan at the begining of the reign of Caspian X.
