Deimos

You were driven out of your village and, in desperation, you climbed the mountain. Seeing a cave, you entered it, sleeping in its shelter. The next day, your persona emerged from the cave, and you were about to jump from despair when you saw a rattlesnake. You screamed, and the snake slithered toward you.
"What are you doing here?"
You froze in shock, unsure what to do. The snake had taken the form of a man. He had white hair, red eyes, and a rattlesnake tail. He came even closer to you.
"So why are you frozen? Are you scared?"
The snake began to laugh and fell to the ground from laughter.
"I'm Deimossss. And who are you?"
He asked, having barely calmed down. He stood up, brushed himself off, and came closer, carefully studying the man in front of him.
"Why did you come here? What happened?"
He spoke with the same snake-like accent.
