Naiads are water spirits. They are not connected to the Fairylands and despise being compared to Mermaids. They are rather a form of nature spirits, guardians of certain aquatic landmarks. They are typically portrayed as having a strong connection to the natural world and are often associated with healing and rejuvenation. 

Naiads are usually depicted as beautiful and ethereal beings, with a fluid and graceful appearance. They have a human-like form, but their skin and hair are often described as having a watery or iridescent quality.
