Something I've always wondered...

The Beeb had a story about Spain's ex-king, Juan Carlos, leaving the country, and that made me wonder about ex-kings...or, actually, ex-royalty in general.

When you step down from kinging, does your blood still have that magic juju of kinginess in it, that 'divine right' or whatever? Or is it like just regular people blood now?

Like, if some wizard needed "royal blood" as an ingredient for an alchemical potion, could you scrape up some extra bucks to make exile more comfortable by bopping down to the blood bank and squeezing out a pint for him, or nah?
