That's official DnD lore for Azer.
Made, Not Born. Azers don't reproduce. They are each crafted from bronze by another azer and imbued with a portion of the crafter's inner flame. Each azer is sculpted with unique features. This crafting process limits the growth of the azer population and is the primary reason that these creatures remain rare.
It sounds counterintuitive, but I think lawful and chaotic should be the other way around. Libertarians (in the sense it's used here) tend to support freedom through fairness and consistency of the law, whereas for authoritarians the law is whatever the person in charge feels like.
