Get the perk know they self if you can, go on a pilgrimage and try to go to as many places that will give you learning lifestyle points, then maybe you’ll live to 66 and can make them knights.

You seem to pronounce slavic languages quite good !

Ok this was one hell of a episode, i will try to help u as best as i can. The ideal choice is to disinherit your first born son and grandson, i know its hard to justify for role play but this is as roleplay as it gets. Ypur wife is the queen of bohemia and Sicily he has influence in ur court more than anyone with the backing of her own kingdom. U will face severe pressure to put one of the twins on the throne however the good thing for u is that both ur kids are 1. Yours and 2. From ur side of the family. In terms of roleplay if u had one son it would make sense for him to just inhiert bohemia but u have the worst luck and had twins. U should also marry the twin that is most likely to inhiert Sicily to your wifes bastard daughter since she is the only kid that is from HER family meaning your entire line of family in bohemia and maybe even Sicily is at risk.
