Naids can be very rude at times, and they like to play feisty tricks. They are also very conceited. When Kendra talks to them, they talk to each other, insulting her, like she isn't even there. Some Naiads can be kind, such as Lena. They are never aware of the future of past, and are instead always looking for amusement. They have no self-awareness. However, when the become mortal, they gain the knowledge of morality. They become more aware of time. They love singing sweet, naiadic tunes.
The Naiads are very beautiful yet they aren't kind. Since they never age in the water, they are always pretty and they possess an otherworldly beauty. As water nymphs and aquatic creatures, their bodies are adapted to living in water and they have thin, translucent webs between their fingers and toes. One was described to have blonde hair and a heart-shaped face in one of the earlier books. The Naiad that grabbed the silver fairy bowl out of the water had pale skin. Naiads can also resemble mortal women of different nations like Lena who had asian facial characteristics.
