Yep, I've already given him up to his aunt to raise (she has the diplomacy path, and the ambitious trait, which is where he got that). I'm thinking I'll probably toss poor Eudes into prison before too much longer so I can kill him off before Herbert croaks. It'll be a negative hit with my vassals, but I'm still small enough that it doesn't really matter.
In other news, the kingdom of Bohemia has formed itself, and is to my knowledge the first Christian kingdom to arise. I recently fired most of my ministers and replaced them with claimants, since it's right around the time in the game (~1080+) that claimants finally start becoming common. I just checked my staff, and my spymaster is the heir to Bohemia, which uses Seniority succession. Hmm...
Here's an updated snapshot of Benoit:
Not much question left about who I'm going to leave behind as my heir...
In-Game:
11 April, 1088:
I am now the Duke of Valois. After much thought, I have had Eudes imprisoned. It pains me to be so cruel to the boy, but he stands in the way of the ascent of our house. The sin is my own to bear, and I do it for all of my kin; I shall pay for it at the hands of He who judges all men.
9 December, 1088:
My son is dead at my hands. May God forgive me.
12 February, 1089:
Benoit has come into his own. Despite the blood on my hands, I feel that I have made the right choice... I shall leave House Karling in able hands when I pass from this world and face my judgment.
(OOC: It would appear that my next character is going to be the 11th century version of Winston Churchill.)
6 March, 1089:
I have secured a marriage between Benoit and Duchess Gertrude of Brunswick. He has left Rethel for her lands to the east. I fear for his safety, but he writes to me to inform me that he has already been made chancellor, and is enjoying great success.
