Reasons why we won't hand the Neptunian throne to just anyone

Most of you are aware of different sort of planet's ways of gaining the throne. In Saturn it's conquests, in Pluto it's riches,  in Jupiter it's by lineage... while in Neptune it's marriage. Yup. We don't care whether you are non-royal. You just need to be somewhat of status, or have a clean record and you might just win the throne. 

As you all know, the recent ruler of Neptune are technically the Elves. Since the King is an Elf. However, since he's not around, the Merpeople have been thinking that it's them who's practically ruling. But no. Unless the throne is handed down to the current prince/princess representative, whichever present monarch (still alive), shall be the ruler. So it's Elves. 

Because of this marriage rule, most royalties from different countries would try their ways into getting my sister to marry them. But we're probably deciding on a normie for safety. The rules are like this (to make things clear)....

Current Monarchs will give the throne to representative when he/she marries ---> Representative is the only one who has the right to be honoured as true ruler of Neptune unless he/she dies (does not apply to normies)

So in case Millie dies, the normie husband can't rule since they are not given rights. And thus, the throne will be given to the next child (or the kids if applicable). 

The reason why we won't give the throne to other creatures? There are people like Lord Zelfir who's been trying to grab the throne since the very founding of Neptune. What if he decides to do something selfish like, say, turn everyone into Vampires? No. We know him, he's really evil. Next are the Sorcerers. Have you seen Sabrina's blog? Really mean. They play dirty, these sorcerers. They will do ANYTHING and I say anything, to make themselves look good. If something shameful happens, they get rid of it immediately. Plus, they're part of the immortal group. A sorcerer will only be given the chance to die, if they're children return the favour of having kids and producing heirs/heiresses. That would mean they would rule for a very long time. 

And goodness NO we wouldn't give the throne to the witches and warlocks. They can't be trusted anymore, unlike the good old days. They don't exactly belong to the immortal group, but they have very long lives as well (like elves). It would be nice to give it to the dragons... but they're also immortal. 

WELLP! Long post but that's me.
