I feel a bit stupid for asking this, being an English student, but I'm in doubt: A tale about wanderers: is "Wanders' tale" correct or "wanderers's tale"?
Correct. The rule for plural possessives being different than that for singular terms or proper nouns that happen to end in s.
Okay thanks! I was doubting... which makes me very uncertain about things and I don't want to get this wrong!
