Recently I've started a new 2nd Edition Birthright campaign. I have three players who all made blooded characters, but none of them chose to be regents.

We've played a few games and they've accumulated quite a bit of gold. Now they're interested in setting up their own domains. To facilitate this I've expanded the bit in the Book of Magecraft that says a Create Holding action can be used as a Free Action by a blooded non-regent character to make a Source (0) so that they can use the Create Holding action to do the same for guild holdings and law holdings.

This solution was the best I could come up with, but I'm worried that I'm not doing this the right way. Given my penchant for missing stuff lately, I've looked over the rules that I have several times and still haven't seen a way for a blooded character to become a regent that doesn't require some sort of investiture. Did I go about this the right way given the circumstances, or does someone have a better solution?
