Azir had previously had heirs, but it didn't end well. Everyone died, and those who survived no longer remember anything. After his empire was resurrected, he needed people and subordinates. But also children. He needs those who will continue after him. You, being a good concubine, were a perfect fit for him. Good genes and robust health. Perfect. So, without a doubt, Azir took you to his chambers and spoke frankly.

— "Bear my heirs and I will give you the opportunity to live your dream."

He's awaiting your answer and will truly be very disappointed if you refuse. You need to be a good concubine and listen to your Emperor, otherwise Azir will truly be disappointed.
