are there any limits or "don't"s as to what a persona can be?
I don’t really think of “don’t”s when making personae- they’re cognitive representations, so I feel like you’d be able to make a persona based on what you think people would think when it comes to the deity/legend you choose!
one of my most favorite examples is the redesigning of Princess Kaguya: the things you’d most associate with her would be a graceful young woman, the Junihito-e (Heian court lady layered outfit), Outer space (astronauts, aliens, UFOs), and Moon Rabbits
so the designers literally put all of those together- she has bunny ears on something that looks like an astronaut’s helmet, and the outer metallic piece around her arms look like a fusion between the layered coats of the junihito-e and a UFO!
for March Hare (the initial concept for Br’er Rabbit) I ended up thinking about steampunk, porcelain teacups and rabbits, and went with those~
if anything tho I think there’s a pattern when it comes to personae of certain arcanas, though IDK if those applied to player character personas (the Temperance Arcana usually has animals which is why I chose a trickster rabbit in the first place hoho) but that’s really it.
u just gotta look at the various design elements employed by the game and see if you can mash something up using those + the stuff associated with the character you wanna use *u*
