One of my favourite roleplaying save is my current one, where I play a Welsh Buddhist Count in Sicily. What's so fun about it is I started my character as an ugly hunchback dwarf with lisp (give me youth, with no risk of revolt from vassals due to only starting off as a count.) Towards the end of his life, my character was able to capture a 17 year old Princess of Lombard. So I made her my concubine. She gave birth to a twin of sons. Two those are a living proof of how the ugliest infidel in the world ravaged the the Lombard Royalty, by ravaging the Lombardian cities. I'd like to think my boys shouted "rape 'em like my father raped my mother!" when as they stand on the ramparts of conquered cities. I've made sure that all my kings now take Lombardian prisoners as concubines. Although I will soon start taking some Muslims concubines for some good old racial mixing.
