He MAY be a Devil

But, what she wanted to figure out was just how the king had given them the knowledge. She couldn't bother less about all the strange terms and machines.

She thought about it for a bit and came to a conclusion. The powers of the king were most likely a devil's. The king must have sold his soul to the devil to survive.

After all, the experience she had before receiving this knowledge was not 'ancestorly'.

What she faced was something terrifying and scary, something that would probably haunt her for years to come.

Maybe to others, what she experienced would just be like how people who watched a horror film would feel. A day or two of slight fear and then everything goes back to normal.
