Naga (Rathnir)

Origin
Nāga (or Nagi", "Nagin", or "Nagini" are also acceptable names for female Nāga). Nāga is the generalized species name of Humanoid Snake Hybrids. Nāga have been around for a few hundred years yet they have no known source, yet there are no lack of theories. The most common theory that many people believe they were created by some god sometime far back in Yimmu-Audal and spread out across Rathnir over time. Others believe  that they have been in Rathnir since the start and only recently came out hence why we have only seen them for a while. Either way, not much is known about the origins of the race and it still puzzles us to this day.

Forms
Nāga's come in many different forms, the most common form being a Humanoid Snake Hybrid that is most commonly more humanoid then snake. Sometimes though different and rarer types of Nāga's are born, such as Nāga's with fully snake bodies and only the head of a humanoid. The rarest form of course being the opposite of the previous with Nāga's having a mainly humanoid body and then a snakes head.

Age & Diet
Other than the mainly visual form of the Nāga the rest is almost exactly the same for all of them. Most Nāga's only live to 25 as they are prone to war, but its been proven they can live up to 100 years, possibly more. All forms except for the Snake headed one are omnivores as they can fully eat and digest both types of food, while the snake headed form can only eat meat due to its fangs.
