Maybe one last thing about Xiyatu…
The dragons are not nice beings. They are not kind, they are not generous, they are not paternal.
They are greedy, calculating, and pitiless. Humans are tools, and they no more grieve for their loss than a you would for losing a screw.
(At the same time, they are not sadists. They don’t glory in human pain or suffering. They don’t torture for the sake of torture, torment for the sake of torment, or play with their food. They are indifferent, not malevolent.)
The dragons increased freedom in the city, because it fit with their goals. They ensured the security of the city-state, because their plans required it. They foster economic development (which brings jobs and a measure of prosperity) because they need a prosperous domain.
None of this is done out of the kindness of their hearts. Dragon hearts have no kindness.
When dragons bargain with you, it is solely because it suits them. If it suited, they would kill you just as easily.
Do not romanticize them, do not mistake them, do not forget what you are dealing with: an entirely inhuman mind, utterly bereft of human emotions. Utterly bereft of humanity.
