Mushroom Kingdom
Super Mario dimension
It was a beautiful starry night in the Mushroom Kingdom. Toads were roaming village streets while admiring the large pink castle up ahead. Just near the gates were two well-known plumbers, one red and the other green. They were no ordinary plumbers, they were heroes.
Mario and Luigi were chatting about their countless adventures, the dangers they faced and how many times that monstrous Bowser had his shell pummeled. Luigi even added his paranormal quests in haunted mansions, which still shook him a bit.
A star in the sky twinkled, catching the brothers' attention. The two watched in awe as the star streaked across the sky. Mario was just about to tell Luigi to make a wish when he noticed something odd. Shooting stars don't come falling down, do they?
The shooting star rocketed down to the world's surface with the speed of a comet. KRABOOOOOMMM! It smashed into the ground meters away from the castle, shaking the very ground. The two brothers leapt up and raced toward the crash site as nearby Toads began panicking.
Mario had enough experience to know this was the start of another adventure. After all, he's had some for more than 30 years! After a bit of running, the two reached a massive crater that sparked with electricity. Motioning to Luigi to stay back, Mario carefully climbed down to the crater with his brother following nervously behind.
Their eyes lit up as they saw something shiny in the center of the crater. A blue crystal that occasionally shifted red had embedded itself into the ground, a powerful glow illuminating from it. Mesmerized, Mario reached out to the crystal in an attempt to pull it out. But the moment he and Luigi touched it…
KKRRRRRZZZZZZZAAAAAAAPPPPPP! In the blink of an eye, the brothers were electrocuted with blue and red lightning and in a single instant, the two vanished from sight…along with the crystal, leaving only the crater behind as two Toad guards rushed up to it to investigate.
Mario screamed as he felt himself falling and spinning through a swirling, blue tunnel that crackled with lightning. He could hear Luigi somewhere behind him…or could he? Before he could even act, the tunnel opened in front of him, revealing a perfectly-blue sky and strange platforms with accompanying architecture.
"WWWWWWAAAAAAAAAAAA…OOF!" Mario grunted as he plummeted from the sky and landed head-first in dirt, his red cap fluttering down and landing on his back. Pushing down on the ground with both hands, Mario tried to pull himself out with all of his might.
With a pop, Mario fell back from the hole he had made when he fell. Shaking his dirt-filled head, Mario stood up in a daze. "Mama mia…" he groaned as he conked his head and put his cap on. One of the first things he noticed was…
"Luigi? Luigi!" Mario called out, only to hear nothing but silence. Apparently, he and his brother had been separated. He had to go find him. Dusting himself off, Mario took off running, jumping onto one of the floating platforms and vaulting off more with parkour stunts.
One of the platforms was long and face the ruins of what looked like a coliseum. Mario looked around, noticing a banner with a crossed circle on it. Before he could study it further, something whizzed past his face.
Mario whirled around to where the projectile had came from to see a figure in green leap at him with a raised sword. Quickly, the plumber rolled out of the way as the figure struck down with his blade. The attacker stood, holding his shield at the ready as Mario engulfed his fists in flame…and charged.
