Nereids are associated with the stormy seas and oceans. They look like beautiful humans but with pearlescent blue-green skin, luminous eyes, and webbed hands and feet. Nereids have no trouble adapting to civilization, but they are a rare sight, because they vastly prefer the ocean to walking on dry land.
