Naga (Ancient)

Naga have a humanoid upper body and a snake-like lower body.
This type of Naga has black skin covered in scales that come in dark shades of nearly all colors. These scales cover almost all of their body. In place of hair, they have thick tendrils. A spiny fin runs down their back.

An ancient kind of Naga, ruling the Underdark long ago, until they were driven to extinction during a demonic Invasion. Sacrificing their entire population to seal the Demon's entryway, only a single one of them - Acalixoxis - survived hidden in the Underdarks Mirror Basin. She had removed her own scales, replacing each with one scale of her people to restore them someday. After the narrowly averted summoning of Kiaransalee and Demon Invasion in the Underdark in 471, this finally came true thanks to the efforts of a group of Radiants.
