"What're young doing here Discord?!"Asked Celestia.
"Don't you suppose to enjoy your life with foods and drinks at Olympus?!" asked Luna.

"Nothing! Just come to say hi! Oh! And before I will go..." said Discord and he's give Princess Celestia a scroll.
"It's from your father." said Discord and he's disappear in the thin air.

"It's look like that you didn't read my mail from Discord." said Zeus.
"Why don't you send Hermes to come in the first place?" asked Celestia.
"He's kind of 'busy'... with a beautiful Pegasus girl in Couldsdales." said Zeus.
"So why are you come here?" asked Celestia.
"As that you see when Lord Tirek had escaped..." said Zeus.
"Cerberus is now start to be uncontrollable and the Walls of Tartarus... start to be destroying..." said Celestia.
"If the mortals still don't pray for the Olympians, we all will become mortals like them.
We all will died and the Titans will escape and destroy the whole entire land of Equestria.
In the air, underwater and the whole entire land. All will be destroyed by the Titans," said Zeus.
"You are asking help from me and my sister?" asked Celestia.
"Me and my brothers need all children to help. But mostly refuse amd take care of themselves only," said Zeus.
"So I'm with them. Sorry father, but Equestria need me and my sister," said Celestia.
"Well... if you reconsider... you know where to find us," said Zeus and he's disappear in lightning.

"BOOM!"
"Father!"Said Ares and he's walk along with two orange Unicorns that are his half-older brothers, Balius and Xanthius.
"Sooo..." said Balius.
"Where're our younger sisters?" asked Xanthius.
"They didn't come," said Zeus.
"Zeus, we have to go now," said Poseidon and he's lead everypony to the Walls of Tartarus.
"Here we are. Tartarus, the most security prison in Equestria," said Ares.
"Hades! Lucifer! We're come to visit your realm! Show yourselves now, please!" said Zeus.
"BOOM!"

"For a long time. The sons of Kronos, had come to meet each other again," said Hades.
"My brother, who thrown me into the Underworld to be a slave of another brother of mine.

"Please... let us help you rebuild the Walls of Tartarus and taming Cerberus for you..." said Zeus.
"Will you agree my love?" asked Persephone.
"Agree with. What about you Lucifer?" asked Hades.
"I'm agree in as well. But... with my own... condition!" said Lucifer and he's shoot red beam to Hades to fall down from the hill.
Then a large dark brown horned Centaur appear on the top of mountain upon them.
"ATTACK!" shouted Dark Brown Centaur and the two upper bodies, pony-like creatures called Makhais start to throw lava to them.
"Poseidon! Watch out!" said Zeus and Poseidon jump to his left and shoot a blue beam from his Trident to a Makhai and killed it.
