I brainrot about them ssjdnfdkksdk

Anna and Elsa:

have a tutor called Erlingur 

There are seven neighbouring isles (might be Britain, Ireland, Iceland, Greenland, Spitzbergen, Faroe, Shetland?) (I’d add Denmark but to my dismay it’s mostly not an island) 

call their mom and dad by Mama and Papa 

Friends with a girl called Rani from a country where there’s 'large sandy beaches' and coconuts

Anna has a horse named Kjekk since she’s at least 15

Elsa has beautiful Penmanship 

Hans: 

hates his brothers like, so much 

Dad too, moms okay actually 

Oldest brother is called Caleb

Parents have been married nearly 30 years

Caleb‘s wife is visibly uncomfortable, 'almost nine months' along with her second, that marriage is a wreck. The first child is a son.

King actually likes that wife (because shes having his grandkid)

lol Hans says he’s not even a spare just a throwaway

The twins are Rudi and Runo, respectively 'average height with reddish hair similar to Hans‘' and 'freakishly tall with freakishly blonde hair that stuck straight up, pale eyebrows, and pale eyes'. He looks perpetually shocked.

the guy self harms I think

People might have thrown glassware at him before 

all the brothers are married with children except the twins and Hans, former two are courting someone I think

The princes are 'a handsome bunch' implied to be ginger and tall (except Runo)

The third brother is Lars, after whom there’s a five-year gap before the next child

Lars‘s wife is called Helga and has never quite forgiven her family for shipping her to the southern islands. She’s implied to be pregnant and doesn’t like anyone here

Hans‘s horse is called Sitron

I think Blavenia and Vakretta are supposed to be neighbouring countries
