Xenoblade Chronicles and Xenoblade Chronicles 2 are being used for artworks featuring Melia Antiqua and Nia, for their (presumed) appearance in Xenoblade Chronicles 3's trailer.
I don't think artworks like post #5123139 should be tagged as Xenoblade Chronicles or Xenoblade Chronicles 2, because they have nothing about them other than the origin of the two characters, but i wanted to ask others' opinion on it before adding the rule on their wikis.
