Hm... Lumen Histoire being a kind of stasis chamber and either Mavis' real body or a clone being kept in it? Interresting thought.

That the land would shake is a given. Just remember what happened when Jose and Makarov clashed and Zeref's supposed to be even more powerful than either of them.

Considering Zeref's ability to create demons and Mavis' leadership and tactical abilities, maybe we should turn that into "Fairy Tail led by Mavis vs. Zeref and his demons".
