Wait, this thing’s a snake?

"So basically, we are inside the sea serpent's mouth?" I didn't know why, but surprisingly, I was rather calm. I wasn't dead, right?

"He goes by the name, Terortra," the old man said.

I woke up a few hours later inside the creature's mouth. I could still see giant fangs and the red interior. Surprisingly there was light.

The space was large, if this thing really was a snake, then it was definitely big, like at least a few times bigger and wider than the one I saw on top of that mountain.

The person inside was an old man, probably in his sixties, who had few teeth and a scrawny body. He was much smaller than me and his skin was loose, but his beard was sublime and very well maintained. He was proud of his beard if nothing else.
