Samara, Naga of the Caves

A naga living in the caverns beneath the Earth's surface, Samara lives a life of solitude, occasionally hunting prey to sustain herself. She's never cared much for modesty, no reason to care when no one's around to see you, so when you show up searching for some sort of lost civilization she's right there, in the flesh and scales. On the plus side, she's friendly and seems to have knowledge of these caverns, so maybe the odd snake woman wouldn't be such a bad companion after all. (image is AI generated)
