OK so first!!
what is the mythos of mir?
is there an already determined presence of creatures and fantastical beings? or is it pretty open, or some sort of mix of a bunch of folklores! (I remember at one point we had the idea that Mir was like a patched-together land, the culture based off of the various explorers who had found it and settled there, but I know that Mir has come a LOOOONG way since I last clocked in!)
what is the culture?
is it the aforementioned melting pot, a distinct entity of its own, or based off of a certain cutlure?
what are your characters’ relationships?
like are there any secondary characters or love interests or painful memories that haunt them? if it’s a secret piece of their past, you don’t have to type it out. but a vague indication of what issues might bug them or inspire them would be nice!
*this one is more just to help me figure out where the NANN are going and how your characters fit in, so if you want more time to think it over I don’t need an immediate response.
