Twilight groaned as she woke up with a pencil imprint fresh on her cheek. She looked around, seeing that she was in her castle library. "How- how did I get here?" she said as she groggily shook her head. "Wait, was that all just a dream?" Twilight said. She had pretty crazy dreams since the encounter with Godzilla, and this was probably no different.
"Twilight, you fell asleep organizing books again." a familiar voice said as its owner knocked on the door.
Was it all just another dream of hers? "Oh, hey Spike. I- I'm awake." Twilight said as she walked to the door, opening it with her claw. She expected to see her dragon tapping his foot in annoyance, but instead, the door was flung off its hinges as an explosion knocked her and the door back, knocking her five feet away and into a recently-organized bookshelf, causing books to pile upon her. She covered her ears as a voice that put the Royal Canterlot Voice to shame yelled out into space.
"RAAAAAAAAAAAAAH!!!"
Twilight gasped as a human man with coffee-colored skin and brownish-black hair, donned with a suit of light blue armor burst forth, setting everything on fire as he walked with a spinning trident in his hands, causing fireballs to go all over the place. "NO!" Twilight said as she jumped out of the way to see the man burst through her wall, leaving a gaping hole and the smell of burning books behind. Who in the right mind would just show up and destroy someone's property?
"Twilight..." a familiar voice said. She panicked and went out the door to see her baby brother laying there. His scales were already covered in the soot, and the smoke was nearly getting to him. "Save yourself..."
"Spike, please don't die!" Twilight said as she hugged the dying dragon. "Don't die, don't die, DON'T DIE!!!" Twilight said as she hugged him tighter and tighter as he cried. Her tears literally started to flood the area, and a fish was seen swimming in the background. "Oh no, not again!" Twilight said as she closed her eyes. With a quiet gasp, she once again went out of bed, silently breathing. "Great, another vision." Twilight grumbled as she went to back sleep again. Fortunately, it wasn't going to be daily, but the bad news is that it is becoming closer and closer, and who is the Stranger's acquaintance? All she wanted after the SpaceGodzilla incident was to have a break at those adventures. Granted, three months was a good break, and comparatively long, but the fact still stands.
"Let me guess, another weird dream?" Luna said as she looked out into the window. Ever since the incident, Twilight's dreams did not run on magic, and thus, Luna couldn't access them. Instead, she and Twilight would talk about said dreams if they turn out to be of some importance.
"Yes, it was. I was studying in the Castle when all of the sudden, this armored human wielding a spinning trident burst through the library, burning everything in his path and burst through my wall." the hybrid pony said with a shudder at this weird human man. He looked similar to the Stranger, but his colorings and clothes say something else. "I don't know who keeps sending my dreams, though." Twilight said, half-lying. She knew the Stranger sent the first vision, but she wasn't sure about the second one. "The first dream, I merely shrugged it off, but I'm positive that it won't be good."
"Hmmm, very interesting. If you have any more of these dreams, let me know. Even though I cannot visit them, I can still decipher the meanings of your dreams." the princess of the night said. Usually, Twilight's dreams were now of a random chance due to her now hybridized nature. But these dreams of flooding were starting to concern her friend more and more. "Perhaps a new threat is dawning, Twilight. You must come prepared." Luna said as Twilight nodded in response. Maybe the threat wanted something to do with the city, maybe that was who the Stranger was talking about?
"I haven't seen anything like it, but after the incident, I think I can take on- woah!" What Twilight had to say was interrupted by the shaking of the ground. Both her and Luna kept aloft with their wings. "Oh no, the island from my dreams!" Twilight said in realization. "It's rising from the sea!"
Meanwhile, in Ponyville, Discord and Fluttershy were having their regular tea, when Discord's body wiggled around as he sensed a magical imbalance. "Oh, that can't be right." Discord said as he felt a huge mass of some strange energy just southeast of the Dragon's Lair.
"What is it?" Fluttershy said to her mismatched friend.
Just as Twilight's dreams predicted, the planet's plate tectonics have awoken once more, and a large chunk of the ocean floor started glowing with proto-magic. A huge storm circled the area, lightning flashed, thunder cackled, and it looked like it was raining, but the sea water was going up into the clouds as a new landmass rose from the depths. First came the tips of the mountains, rising as the spare water started going back up into the clouds. At that point, they looked more like a barren, sandless set of islands than anything.
A thousand feet later, new grass started to grow rapidly until it looked like it was always there. Pretty soon, the rising mountains gave way to a dense jungle, rolling hills, and eventually, the valley began to take shape. A bolt of lightning struck a newly-formed glacier, causing it to partially melt and give rise to a waterfall. The new river flowed down the island's valley, cutting through the jungles and snaking its way through lakes and around hills.
Pretty soon, something else rose from the depths of the seas. The first metal spires of a lost city were unearthed from the surface of the ocean. Then, came the red tiles of the highest roofs, some of which were still covered by some stray seaweed that managed to latch onto its foundation, and finally, the roads were unearthed. At the middle of the central plaza, a mosaic of a trident lay, one that remained intact for millions of years, buried under sediments and water. With that logo, there was no mistaking this city for anything else.
The lost city of Atlantis has risen from the depths.
