Asmodeus cared greatly for his mother.
She was a demon queen and one of the most frighteningly unsettling women he had ever seen before, but she was very kind to him.
When all of his other siblings were already born by Lucifer's other wives, Igrat alone had yet to conceive.
This made her miserable. So much so that from the day that Asmodeus was finally born underneath a qlipoth, she doted on him endlessly.
Most demon mothers' idea of being nurturing is borderline torturing their children to make them big and tough.
However, Igrat had no intention on nearly breaking the one thing she never believed she would get.
So, instead she spent lots of time with Asmodeus.
Igrat told him her dreams for him and his future, not to mention the her hope that someday he would be the one to lead Hell's armies through the gates of heaven and burn it all to ash.
