The wishmasters... They were believed to be extinct after a war that nopony knew. But they have returned and they are hungry. They return and drag everypony in Ponyville to their hometown because one little colt who has moved to the Ponyville recently made an inaccurate wish.At their hometown ponies are getting dragged to the central tower where their wishes and desires are being read. None of them were in the "right condition" untill the queue comes to Twilight. Gladly by that time she has got a clue who they were and made a wish.
