being vague works just fine for jamjars where the characters aren't already familiar with the world

but in an au the characters would have been born and raised there so you can't exactly get away with vagueness

if you want an ic excuse for you not bothering to read oocly just play a character from a different kingdom so you don't have to bother actually reading the info but don't advise someone to NOT tell us about the world just because you're lazy
