Nixies are small water fairies. As far as anyone knows, all nixies are female. Most nixies are slim and comely, with lightly scaled, pale green skin and dark green hair. They often twine shells and pearl strings in their hair and dress in wraps woven from colorful seaweed. Nixies prefer not to leave their lakes. A nixie stands about 4 feet tall and weighs about 45 pounds.

Nixies are fey creatures, and thus unpredictable. However, they are rarely malicious, attacking only when they feel threatened.

Nixies are fey creatures related to sprites that make their home in freshwater lakes. They appear as strangely beautiful humanoids with lightly scaled greenish skin and webbed hands and feet. Their eyes are silver and their hair is dark green, and they clad themselves in garments of seaweed. Nixies speak their own language and the common tongue. They also appear to be able to communicate, at least on a rudimentary level, with freshwater fish of all types.

Nixies are weak in combat but make up for this weakness by attacking en masse and overwhelming their enemies. They favour fighting with long daggers and long darts which, due to the nixies short stature, function as spears in their hands. Nixies will melee with these spears underwater and above water they will hurl them like missiles then melee with their daggers.

Nixies fear bright light and fire, their aquatic nature makes these things foreign to them and a strong presentation of either will drive them away. A strong light source presented underwater will be obscured by schools of nixie summoned fish surrounding the spell effect.

Nixies lair at the bottom of lakes, where they weave living seaweed into dwellings. These dwellings blend in with the underwater growth so well they are 90% unlikely to be noted until within 20 ft of them. These underwater villages are guarded by either 1d4 giant gar (25%) or 2d4 giant pike (75%) which will obey commands from the nixies (see: Fish, Giant). Nixies can venture onto dry land but do so only with great reluctance.
