Kingdom of Knuffel

You're going to end up adopting a lot of owls, more than you can handle

To transform into the most beautiful princess every night

You're going to be asked to be the fairy godmother of the next queen of the kingdom

You're fate is to map all of the stars and find new constellations that will make your name famous.

You're going to be published and get the recognition you deserve

You're fated to be known as the school's mystery #9, a young girl in band club that died due to being heartbroken

You're going to become a top idol in the Kingdom

Stars shiny brightly... for a time. What's to become of them afterwards?
Some grow so intense their only path forward is becoming a celestial firework.
Others exhaust themselves and turn into a negative version of themselves, which only attracts darker souls. And that is, I'm afraid, your fate: you'll become darker and darker, a leader for all that is obscure.
That is your unexpected fate.

That's a very interesting story.

As for you you've been exiled from your underwater Kingdom and is now pretending to belong in the mountains

Your fate is to go into war. You will be victorious, but seen as evil because of how you won the battle.
