I am not just a king, as I have already said. Since apparently you all need it spelled out for you, I am Pharaoh, and like all who ruled Egypt, the blood of the sun god Ra runs in my veins. Do not speak to me as if I am unfamiliar with such a world, ghost king. I know it well.

And I will have you know it was your very gatekeepers who asked of my help. They wish for me to devise buildings for them to construct.
