pros of spm lore: you learn about dimentios family line
cons: you learn hes human
cons: you learn hes human

for anyone wondering dimentio is related to the magician line, and the magician who created the pixls had a daughter with a "human spirit" so the magicians have to be humans. its one of the 15 stories carson talks about it in game if you give him 10 coins
even if you say "oh the daughter being transferred into the pixl is just a theory carson talks about its not confirmed" it doesnt change the fact that he implies the magicians daughter is human by using her to refer to the spirit in the pixl
