Stuff to Know: Probably the most important thing you need to know about Nymphs is they are a genderless species. Neither male nor female, they mate through a connection of the nervous system, allowing them to produce with each other, as well as both males and females of other species. However, children that come from other species are often infertile themselves, unless they somehow inherit the reproductive system of the opposing species. This is unlikely, however, as most Nymph genes are dominant.
“Thay’la” is essentially their word for parent, considering they don’t have the typical mother/father dynamics. The half of the couple that did not give birth is typically known as “Tha’len”.
They’re not a warrior culture, but when it comes to stealth or guerrilla warfare tactics, they’ll mess you up. They mostly make good spies, though their clans VERY rarely war with each other so it’s only the outcasts you’ll see doing that kind of work.
Traits: Nymphs have awesome night vision, pro flexibility/agility, and they basically glow in the dark. Okay not really, but their coloring changes a lot in the moonlight in comparison to the day, where they look washed out and faint. They typically don’t grow much taller than 5’2”, the average being closer to around 4’9-11”. Beyond their coloring, their most obvious physical traits are long, pointed ears and a lack of body hair. Full-blooded Nymphs don't even have eyelashes.
They also have a strong affinity to nature, though if that comes from some sort of power or merely the fact that they've lived in forests for generations is debatable. Other than that, they don't have any particular power or ability in their blood.
Societal Perception: In ancient times, Nymphs were almost all blessed by Magic. They mainly dwelled in swamps due to the large amount of life within them, were very mysterious to other cultures, and showed themselves mainly at night due to being largely nocturnal creatures. As a result, they were often blamed for the deaths of anyone who happened to get lost within their murky territories. Throw in the Nymphs who abused their powers, and it was perceived they were evil beings, even demons who had come to walk the planet.
Fast forward a few hundred years, and Nymphs no longer have the same high level of magic within their blood they once did. They live mainly in forests instead of swamps, and rarely venture outside their own clans. However, the stigma of their culture has only gotten worse. Called “Dream Terrors,” "Fearspawns" and a slew of other evil-related slurs, their most common nickname is "Night Crawlers," to the point that many don't even realize it's a slur and not the actual name of the race. Nymphs are generally considered to be creatures of bad luck, bringing with them nightmares or even mental disease. None of that is true of course, but the result is all the same, and the uneducated masses usually greet Nymphs with anything from disdain to outright fear.
(I was too lazy to write anything specific to their culture, but this is the important stuff.)
