Yes it's dangerous I did it once with one who was really competent and loyal and it did end up badly (I mean I won but he did rebel) No son you could give this to? I like to keep revoked titles in the family as much as possible (yes I am a mad dynast!)

my sons aren't of age and i haven't tried landing 8 year olds yet, but now that my brother, landed by the last ruler to keep it in the family, has created a faction against me i'm concerned about it lmao
