Ok, I was thinking about familiars, and about the fact that it seems to exist a connection between them and arcana patrons. It seems that your patron arcana could influence which creature becomes your familiar. To put it in context, these are the characters whose familiars we know:
Asra, Faust (snake). Patron: the magician (fox).
Nadia, Chandra (owl). Patron: the high priestess (owl).
Julian, Malak (crow). Patron: the hanged man (crow).
Muriel, Inanna (wolf). Patron: the hermit (bear).
Portia, Pepi (cat). Patron: the star (cat).
Lucio, Mercedes and Melchior (dog). Patron: the devil (goat) + the fool (dog).
Aisha, Chimes (snake). Patron: the lovers (snake).
Salim, Flamel (snake). Patron: the lovers (snake).
Morga, Jaeger (eagle). Patron: the chariot (cheetah).
Nafizah, Darude (turtle). Patron: the world (turtle).
From these 10 characters, 7 have a coincidence between familiar and patron… which means that even though the familiar does not depend exclusively on the patron, it is influenced by it.
The most interesting case is Lucio. As we know, his patron is the devil… in this case, familiar and patron do not coincide. BUT, as stated by the devs, patrons can change with time. Lucio’s patron changes in his own route, and he becomes the fool… which DOES COINCIDE with his familiars. And this makes me think that familiars are influenced by patrons, but also a familiar is indicative of the arcanas that have a strong connection with a person.
If this is true, Asra would have a strong connection not only with the magician, but also with the lovers. Muriel would have a strong connection with the moon. And Morga could have a strong connection with the sun. I think this gives extra information about the characters :D!! (For example, that love and connection is incredibly important for Asra, or that Muriel has a connection with what’s hidden, illusions and doubts). Lucio confirms this theory.
It is also interesting that all known familiars are an animal represented by one of the arcanas… which makes me think that there are certain creatures that form connections with humans more easily than others (specifically, those creatures that are represented by one of the arcanas).
