I mean they’re guardians This is my opinion but guardians live a long life to protect the royal family right-? So i don’t really know maybe Guardians change Masters everytime one of the royal dies or Like they each have their own (Also pardon my Bad grammar/Spellings or anything english is not my first language)
I think you miss the story about.. when the master dies... The guardian die as well... Remember why the king gave the queen his guardian? Technically guardian help the master, it might be in terms of health, power or the long life or even the way they grow up fast... remember the princes are just 13,15 and 18.. but when they turn(forgot the term) it makes them grow faster so they are younger than they look but will retain the youth look afterwards(king) the twins just look small because they are half blood so they will look normal.. and so remember when the queen dies the king's guardian which he gave to the queen die as well...
The only question is they are twins.. would guardian dies if one as welll dies... So yeah they are the same age.. birth the same time and will die the same time
I like this story but the feeling of Arjen who is basically 5yearsold in this world will fell in love with the guardian no sorry. I usually don’t care about the age gap but the way they look i don’t even think i can see them flirt Yeah sorry but if This gets too Lovey dovey i might drop it
