Looking at a few points 1. "Do fairy's have tails?" 2. Fairy Tail's symbol. (possibly derived from "dancing fairy" - search the term in google image) 3. Zeref going on a haitus after realizing the importance of life. 4. A dead Mavis, possibly thanks to Zeref. 5. Mavis and Zeref in a friend-foe relation. 6. Definition of "Fairy", only some aspects taken as per conviniece by Fairy Tail's author probably --- inprired and included accordingly into storyline. a. describes any magical creature, including goblins or gnomes: at other times, the term only describes a specific type of more ethereal creature or sprite. --- broad defition includes creatures with and without tails b. They are generally described as human in appearance and having magical powers, noted for their mischief and malice --- Fairy Tail guild c. iron is like poison to fairies, and they will not go near it --- Gajeel initially d. protection from their malice, by such means as charms of rowan and herbs, or avoiding offense by shunning locations known to be theirs --- Grandine e. Diminutive fairies of one kind or another have been recorded for centuries, but occur alongside the human-sized beings --- Mavis f. These Siths or Fairies they call Sleagh Maith or the Good People...are said to be of middle nature between Man and Angel, as were Daemons thought to be of old; of intelligent fluidous Spirits, and light changeable bodies (lyke those called Astral) somewhat of the nature of a condensed cloud, and best seen in twilight. These bodies be so pliable through the sublety of Spirits that agitate them, that they can make them appear or disappear at pleasure --- Mavis agian with Zeref being the Demon.

Mavis died protecting the One Magic (last real fairy - since they can use magic) using her own life for powering "Fairy Sphere" from Zeref who was trying to kill it to be the most powerful. Thus Zeref was taught a lesson of protecting Nakama (friends) by Mavis just like we see Fairy Tail doing it now causing him to go into self-exile.

That's my view anyway, let's see what happens. All this is assuming 1. Originally only dragons and fairies could use magic. 2. Zeref and Acnologia team up to beat them and one succeeds. 3. Only fairies could teach magic, dragons modified them to create Dragon-slayer magic.
