TriCrown

In the case of the Crown Minor inheriting the titles of Crown Major and Crown Accessory at the same time, a dillemia called the TriCrown may occour if the incumbent holder does not have an heir and/or spouse.
The positions, due to bad forsight in the writings of how Droo’s triarchy should be run, cannot, under any circumstances, be vacant. This means one person could have the power of an absolute monarch even though Droo is a semi-consitutional monarchy.

If all three crowns of power were merged like this, there would be no telling what could happen. This happened for 2 days when the incumbent Crown Major (and last Crown Accessory, as the positions can never be vacant) died (but later came back to life with the help of Cthulhu) and passed down to the Crown Major, making him so stupidly powerful that Droo’s parliament was scrambling to figure out what would happen, as the monarchy of Droo has been going on for 3,500 years and this has never happened.

This has never happened because the incumbent Crown Minor usually has a system set in place to automatically transfer the others powers to his heir and spouse. No previous monarch had ever not had a living spouse, plus the Crown Minor’s heir did not get the powers transfered.

After three days, the king abdicated the throne back to his mother, who had previously abdicated a year ago, and the Crown Accessory back to his father, who had been brought back to life using shady Cthulhu magic.
