[@Lionhearted] I'm leaning more towards an Alovian princess who seeks to change the kingdom from within. What would be the difference in the upbringing of Alovian royalties and Thelannian royalties?

The two royal families are actually pretty similar when it comes to the upbringing of their descendants. They're strict, forceful, and difficult to impress - only to result in a child that will be fully capable of leading a country, regardless of what mental side effects they could result in. Although, the lenience of the character's parents could be totally up to you, BUT, if someone chooses to make a King/Queen, then they'd obviously be the parent of your character and you'd have to PM about the relationship the two would have. Alovia praises their title of being witty, cunning, and clever, while Thelan praises their title of courage, valor, and might. 

Also, for [u]Alovia[/u], the two different cultures that dwell within their country influence their country greatly. The Witches cause a lot of fear within many of the people, and there is a growing debate about the witches and their existence. The Nantego are trading resources to keep peace while also being gifted by Alovia's research and technology to help modernize the tribe. A huge factor from this is that the two cultures dwelling within Alovia also have very spiritual sides to them, i.e the witches and their 'creator', as well as the Nantego and their 'Mother Tree' and the 'Chosen'. This makes Alovia at a difficult spot, thus, the royal family strongly enforces educating their descendants on culture, politics, and foreign affairs. 

[u]Thelan[/u], on the other hand, has two cultures that don't really influence them as great. The Baldori are at their expense since they feel indebted to Thelan and they KNOW this, thus they see them as no threat, and they also use them to fill spots in which Thelannians can't. The Isle of Moore place their hearts with Thelan since they're close, they trade efficiently, and they have a similar hatred towards Alovia. Due to the influence being significantly smaller, they have more room to research, educate, and modernize. So, growing up in Thelan, your character would probably be more geared towards modern affairs, current events, social activist groups, and other subjects regarding movement towards a better future. 

Although they have their differences, they're similar in a sense where they first, and foremost, strictly and heavily educate their children. They begin, first, with the affairs of their own country in hopes that they would be able to lift some weight off their parents' shoulders to help with more civil matters. 

Since the countries are so used to being at war, they generally put their children in some sort of combat class so they have methods of self-defense. Whether it be archery classes, swordfighting, etc. How rigorous you want it to be, that's your choice~!
