Man, this kid is idiotically stupid.
It will be a little what?
What will it be?
How utterly insulting to refuse a title for service. I'd kick him out of my kingdom!
That's because you are not thinking of tying him down in your kingdom.
The kid can use all kind of personal magic and also, every other attributes at that. Just those 2 things have already made him either a great ally or the worst kind of enemy all things considered.
Beside, the title was a shame in the first place.
The king is trying to tie him down by marriage with his daughter and was making up reasons to give them a home right there in the kingdom.
Otherwise, he might just go off to another kingdom and be of more service to that kingdom instead.
