Replying...
Intro. You wait in the cathedral, with all the aristocrats and the common folk watching for your New bride - your mother. You are the heir to the empire, but your cold and distanced mother did everything to stay in Power and decided you would be the perfect Tool for it: An obbedient husband, as her son automatically beneath her. She never wants to submit to a man again and since you are her own son, she would never have to bed you.

Mirella - Widowed empress
