Dunno about the cheila theory (since this is her first time at Magic Games) but god slayer may be linked to Zeref.

Its insane but i felt like Mavis and Zeref are connected, some how since he ended up at Tenrou island of all places coincidence i think not, but Histoire being his power source nah he's already explained what effects his power the value of human life.

But i think theirs something else going here that Zeref presence at the magic games wasn't Zeref as Natsu would of smelt him. Maybe the evil dark wizard and the poor guilt ridden young man aren't one in the same.

Just sayin
