[X] yourself of course
[X] your wonderful brother Iancu will go in your stead
We must lead them ourselves for diplomatic reasons, we can leave Krorod at home to help defend (with nothing) and plan for the conquest of that keep later on. Wouldn't due to send the dwarves the message that we don't care about them by sending an ogre to work with them. Maybe it would work, maybe not. But with dwarves... better safe then sorry.
However, I think we should take Iancu with us, so we can keep an eye on him and make sure we both grow. Clearly we are the better leader, but we need to train Iancu up to be better than "the little brother we promised mother we would take care of". We must make him a grand and important part of our rise to power.
Surely, both of us leaving would have no consequences of any nature. None at all. Not a single one.
