I doubt Zoldeo holds anymore relevance to the story after Tenrou Island, I still think it was Jacob who was behind the whole thing, why else would Brandish join the Spriggan 12 later when Zoldeo had no affiliation to Zeref or Alvarez. Chapter 466 was called "Assasin" which obviously refers to Jacob, I think is was behind this whole situation.
