alive, from what I'm getting at the start of the chap.
The only reason why everything was killed/destroyed in the future was because of the gate opening and not being destroyed.

The 'time' that the chapter is in atm is the present, past of the future(lol).
Since the gate is destroyed, the future is changing, being remade from the present.
History is being remade in the future, so the surrounding will probably pop out of thin air....like...magic...get it..because its fairy tail....heh...heh...heuahauehha..

so.....like...another parallel universe.

Gate Still Intact
