Naga
It’s a Snek
Naga have humanoid torso and the lower body and head of a serpent. Naga also possess poisoned fangs, and they themselves are immune to poison.
Dark Alchemy and a Debt of Blood
Naga practice mystical experiments deep in their citadels. Their greatest success and failure occurred during the last war. The Naga mystics unleashed a curse on the humans of Thalasitae. What they hoped would be a deadly curse instead created the Revenant
The Ends and Means
Masters of poison and deceit, few who cross a naga live to warn others. As cold and calculating as their serpentine brethren, Naga respect practicality and disfavor abundance of emotion.
Naga look to results to justify actions many might view as cruel. Though usually considered an act of evil, Naga have been known to raise the dead for use as laborers. Rumors also abound about wayward travelers succumbing to Naga slavers.
