I have a character in mind, a Santeria priestess (santera) and I want to make her be an immortal or something along those lines. I don't want to do the stereotypical, expected thing where she's an Orisha in hiding. I want something more magical but not in the god realm. I was just wondering what kind of mythological creatures there were (like the Black Dog, etc) in Latin American cultures, Cuban specifically if possible.
I googled Latin American folklore, Cuban mythology, Caribbean mythology and various combinations of those terms.
