Heroes of Olympus and Equestria

Twilight Sparkle POV

Today was like any other day for Twilight.

She and her assistant Spike were walking down Ponyville and everything was just a normal day. Yes, everything seemed like a normal day and she walked cheerfully down the streets.

Then, as she was walking, something suddenly caught her eye, lying in front of her was a creature and it did not look like any creature she had ever seen before. She was not sure what it was so she went to look at the creature.

It seemed to be wearing something and lying besides it was another creature that looked similar to it except that it's face and hair was different.

Twilight remembered reading from a book about humans and it said that they were creatures that stood on two feet and most certainly to her, the creatures in front of her were definitely humans. "What should we do about them and what are they?" asked Spike.

Twilight pondered this for a while and she looked at them again. The humans didn't look dangerous at all and if she took them in, what bad could possibly happen? "Let's take them back home," said Twilight Sparkle, "I want to learn more about them and I hope I can dig out that old book on humans," she said.

Spike acknowledged her word and he went to help her drag the humans back to the library.

Shortly after they left, a huge boat came floating down from the skies but by that time, she was already investigating the two humans.

Percy POV

Percy was having nightmares and it was not the first time he had them but the nightmares seemed to be telling him something.

As he was taking deep breaths in his dream, the dream suddenly changed. He found himself inside some kind of cave and it was rather scary for a cave.

Percy then heard a conversation and then he saw three creatures gathered.

One of the creatures looked like a unicorn but it had black wings and wore blue armor and was surrounded by a blue aura while the other also looked like a unicorn but its horn was jagged and it had insectlike wings and its hooves had holes and when Percy looked closer, they appeared to be female.

The last creature among the three creatures had the head of a donkey and several mismatching horns and limbs and it had a bird wing and a bat wing.

"Discord" said the black winged unicorn to the mismatched animal. "Nightmare Moon," said Discord. "Why have all of you come here?" Discord asked them.

"I heard a voice commanding me to go to this cave," said Nightmare Moon. "So did I," said the insectlike unicorn, "And it sounded just like the same voice that told me to impersonate Princess Cadence and take over Canterlot," it continued.

"It is because I am the same voice!" rang out a voice which echoed through the cave.

The three creatures all shuddered at hearing the voice and to Percy, it was Gaea's voice.

Then, in front of the three creatures arose a humanoid figure and it was a manifestation of Gaea. "Mother Gaea?" said Discord when he saw her. "Yes, my son," she said. "You know her?!" Nightmare Moon and the other creature said with surprise. "She is my mother," said Discord. "And you, Queen Chrysalis," said Gaea to the insectlike unicorn, "You nearly succeeded but ultimately failed but your Changelings will make a fine addition to my forces," she said. "As for you, Nightmare Moon,"said Gaea to the black winged unicorn. "If I never convinced Luna to give in to her jealousy, you would never be in existence,"

"So what happened with the Gigantomachy?" asked Discord. "It didn't end that well but now that I am awakening, I have revived many of them and recruited new minions," replied Gaea.

Discord grimaced at that fact. "Do you want to know what exactly happened right after those troublesome alicorn sisters imprisoned you?"

Discord hesitated for a moment, before Gaea said, "I released some more of my children, the antialicorn brothers, Aitselecon and Anules, the opposites and Banes of Celestia and Luna to overthrow them and like Giants, they can only be killed if a god and demigod work together or a unicorn or Element wielder and alicorn work together, but then, a young unicorn intervened and destroyed them and around the same time, the Gigantomachy was defeated and I slipped back into a deep sleep,"

"You did that all for me?" said Discord with surprise. "I am willing to do anything to protect my children,"said Gaea.

"The reason why I brought all of you here is because the bodies of Aitselecon and Anules were cast here after their defeat and I need you to revive them," said Gaea.

"No problem," said Discord and he snapped his fingers and the instant he finished, the eyes of Aitselec and Anul opened. Aitselec looked like an alicorn except that he had dragon's legs and wings and his mane was fire and Anul seemed to have a purple aura floating around him and he also had dragon wings and legs, wore grey armor and bore a slight resemblance to Nightmare Moon.

"So that's what antialicorns look like and unicorns with wings are called alicorns," thought Percy to himself.

Once the two antialicorns saw Gaea, they instantly bowed and said, "We are here to serve you, mother, what is your bidding?"

"You will remain in Equestria and work with Nightmare Moona and Queen Chrysalis," said Gaea. "What about me?" asked Discord. "Porphyrion will tell you," she said before vanishing into the ground.

After she had vanished into the ground, a hole appeared and out leapt what Percy assumed to be Porphyrion. "The King of the Giants," thought Percy Jackson when he saw the Giant King. "Discord," he said. "Porphyrion," said Discord.

"So you're the king of the giants that Gaea was talking about," said Discord with a smirk. "Indeed and I am also the leader of Gaea's forces, second only to Gaea herself," he said. "No, I should lead Gaea's forces since after all, I actually succeeded in ruling something and I am older than you since I was born along with the titans," said Discord. "No! I am!" Porphyrion shouted back.

The two argued while Nightmare Moon facehoofed and Percy thought to himself, "Oh boy,"

The argument was soon broken when Gaea materialized out of the ground again and said, "Enough, you all can lead my forces but listen to each other," before dissappearing into the ground again.

"Come with me," said Porphyrion to Discord. "You've got more work to do." and Porphyrion caused a hole to form underneath him and he and Discord jumped into it. Then, Percy's dream ended and he awoke with a pant.

He looked around him and saw that he was in a library and standing beside him was Annabeth and a unicorn but it looked incredibly cartoonish for one and beside her was some kind of lizard.

"Where am I?" he demanded.

"My name is Twilight Sparkle and you're in my library but if you want to know the land that you're in, this is Equestria," the unicorn said. "We took you here," said the lizard. "Your friend, Annabeth told us many things about you," said Twilight Sparkle. "So that means I won't have to explain all about humans right?" said Percy. "Right?" Annabeth walked up to him.

Also Seaweed Brain, Twilight Sparkle is the reason why we're here. "What!" said Percy with anger. "But it was an accident," she said. "But what were you doing before I accidentally sent you both here. Percy then told her the whole story about the Prophecy of Seven, Gaea's reawakening, the Giants, and what they did in Rome before heading for the Doors of Death.

By the time he was done talking about it, Twilight Sparkle's and Spike's mouths were wide open in awe.

The moment was broken when the door flew open and a pegasus was standing there but it had a rainbow mane, a cyan fur and looked cartoonish.

Twilight, you should come out and check this out, there's something coming," it said. "You're going to make another Sonic Rainboom, Rainbow Dash?" she asked. "No, it's something better," she said but then she noticed Percy and Annabeth. "Who are they?" she asked. "Long story," she said.

Percy and Annabeth then ran out of Twilight's library and went out to see and when they got out, Percy saw a lot of ponies all looking at an object coming down towards them. It was a huge trieme and it looked familiar. "Wait, is that the Argo II?" said Annabeth right before the ship landed.
