Ahoy~ I'm back!
Determined to save the village, Gray uses his Ice-Make to melt the ice, however, he finds the Eternal Flame to be almost gone afterwards. Natsu, who is in the midst of a battle, directs his flames to resurrect the Eternal Flame, defeating the Cyclops Monster in process. The Eternal Flame, revealed to be Atlas Flame, then proceeds melting the ice in the village, saving it.
Summary :

With
Gray thinking he can melt the
Eternal Flame,
Natsu takes on the
Cyclops Monster, initiating with
Fire Dragon's Claw and effectively knocking it back. However,
Cyclops retaliates, clutching
Natsu with its talons before throwing him up in the air. As
Lucy starts to worry,
Natsu clears her worries and proceeds by attacking the monster with
Fire Dragon's Brilliant Flame.
Meanwhile, while on the run, Gray is still wondering about the mysterious properties of the ice he used through his body to defeat Doriate. Now arriving at the Eternal Flame's location, Gray uses his Ice-Make to thaw it. Such act proves to be efficient as steam starts coming out of the frozen flame, eventually being melted completely. However, as it gets melted, it appears that there was nothing in the ice at all, devastating everyone in the process. As Gray starts blaming himself, Wendy senses presence of powerful Magic, turning out to be right as the fire appears at the thawed altar, albeit very weak, requiring Natsu's flames to rejuvenate it. Due to that, Lucy calls for Natsu, who is still fighting Cyclops, with the latter starting to use his Eye Beam, moderately damaging him while others dodge the attack. Changing his focus, Cyclops gets about to use his laser on frozen giants. To prevent that from happening, Natsu uses his Fire Dragon's Roar, redirecting its laser and greatly damaging it. Natsu then bounces off of one of the giants' head to propel himself to the monster, dealing massive damage on impact. Continuing his assault, Natsu uses Fire Dragon's Brilliant Flame and causes a rain of fire, shaking the ground and alerting everyone present in the village. Ultimately, Natsu uses his Crimson Lotus: Exploding Flame Blade, defeating the Cyclops Monster once and for all.

Also, by doing his attack,
Natsu manages to bring
Eternal Flame back to its former glory. Wanting to see it from the sky,
Natsu tells
Happy to carry him up in the air. He then says that the voice has been coming from the fire itself all along. After that,
Eternal Flame turns out to be
Atlas Flame, his soul being shaped in the current form with the use of
Wendy's Milky Way.
Atlas recognizes
Natsu as
Igneel's son, but is unable to recollect any memories about his past, most likely due to being frozen for a very long time. Expressing her curiosity,
Flare desires to know want happened and
Atlas replies by telling everyone that the whole village was frozen by a single human, greatly shocking everyone in the process. Going further with his story,
Atlas states that such person was a
Devil Slayer, having mistaken him for a
Demon and thus freezing him solid. Despite all of this, Atlas still can't remember who the exact person was. Nevertheless,
Flare begs for his help on thawing the village. Being the one himself who created the village in the first place,
Atlas Flame starts radiating heat, all the while suddenly remembering about everything he forgot about, including
E.N.D., the strongest
Demon from the
Books of Zeref whom even
Igneel didn't manage to defeat.

Having done his job,
Atlas Flame manages to melt to whole village, elsewhere making
Erza happy while angering
Minerva, who gets away, telling
Erza that she'll settle the conflicts with her eventually. As
Erza tells her not to get consumed by the darkness for the last time,
Minerva doesn't listen, stating her desire to cover the whole world in darkness. Back to the main group,
Flare starts crying, happy to see her home being brought back to life.
Atlas Flame then disappears, with everyone paying respect for his noble act. Briefly after,
Gray remember about the
Devil Slayer Atlas was talking about, soon turning out to be
Silver, who is paying a visit to a grave. At the same place,
Tartarus messenger arrives to tell
Silver about his obligation to return to the headquarters as soon as possible, being intimidated by the former at the same time.
Silver then clears all the intimidation by telling the latter that he only occupies himself with Demons.

No one knows the reason why XD
