I don't have the mental capacity right now to find it, but the Job-ed out WoLs in the End of an Era and A New Beginning scenes were never in-game NPCs, although they were the characters from various other FFXIV cinematics, mainly the original one with the Malboro fight. The story is something like the Hyur had the Echo vision of that party and eventually went out to find them. Most of those characters (except the male Elezen) became the party members in the EoaE and ANB scenes. I can't wait to see more of Derpy-Hyur, as I'm sure he'll be in the first expansion's cinematic trailer.
