Xoruxshy sighed, the mountain of paperwork before her threatening to topple over like a house of cards. As the Goddess of Mobius, her duties extended far beyond heroic battles and protecting the innocent. Today, however, the enemy was bureaucracy, and her weapon of choice – a red pen with a chewed-off cap.

Suddenly, a holographic display flickered to life above her desk, its digital chime jarring the silence of the Basilicom's administrative wing. "Quest Activated: Investigate the New World," the message blared in a synthesized voice. Below, a list of enticing rewards scrolled: "Gamer System Mark 1.5 Update – Adds Leveling System, Skills, Stats, and an AI which you can name."

Xoruxshy's brow furrowed. This wasn't a typical Mobian quest. A new world? This could be a game-changer, literally. But the warning below the rewards list sent a shiver down her spine: "Warning: Once you complete this quest, you cannot go back to Mobius for an unspecified amount of time."

Fortunately, Xoruxshy had prepared for such an eventuality. Months ago, anticipating the possibility of extended absences, she had contacted Tails. He, ever the ingenious inventor, had created a "Power Ring Pool" system – fueled by the boundless energy of Sir Charles, Sonic's ever-optimistic uncle – that would automatically generate a fresh supply of rings every hour. Rings, the lifeblood of any Mobian hero. Additionally, she'd entrusted Aunt Sally, ever the capable leader, with overseeing the Basilicom's day-to-day operations during her absence.

With a relieved smile, Xoruxshy activated a communicator. Tails' familiar, cheerful face flickered to life on the holographic screen. "Hey Tails, just letting you know I'll be heading out on a trip. Aunt Sally's on top of things here, and the Power Ring Pool is good to go, right?"

"Absolutely, Xoruxshy!" Tails' twin tails swished excitedly. "And hey, if you find any interesting tech on this trip, don't hesitate to send it my way for analysis!"

Next, she contacted Aunt Sally, who, despite being Sonic's age, still possessed a regal air and a sharp mind. "Aunt Sally, just wanted to give you a heads-up. I'll be away for a while, but the Basilicom is in your capable hands." Sally simply nodded, a knowing glint in her eyes. "Go forth and conquer, Xoruxshy. Mobius will be here waiting for your return."

With a final wave goodbye, Xoruxshy made her way towards the World Hub, the section of the Basilicom dedicated to interdimensional travel. Gone were the swirling vortexes and chaotic energies of the past. Now, a series of majestic doors stood sentinel, each glowing with an otherworldly aura and leading to a different dimension. Front and center, beside the familiar swirling blue portal leading back to Mobius, stood a new door.

This door was unlike any other. Its imposing form was crafted from dark metal, the surface etched with a pattern that resembled a motherboard's intricate circuitry. Four segmented panels glowed ominously – purple, black, white, and green – separated by stark black metal plates. Curiosity piqued, Xoruxshy cautiously approached the door.

As her hand brushed against the cool metal, a blinding flash engulfed her. She squeezed her eyes shut, bracing for the unknown. When the light subsided, she opened her eyes, expecting to find herself in a fantastical new world.

Except, there was no ground. Xoruxshy flailed her arms wildly, a yelp escaping her lips as she plummeted through an endless expanse of white. Just then, a figure collided with her, sending them both tumbling in a chaotic blur. The last thing Xoruxshy registered before darkness consumed her was a flash of purple hair and a bewildered cry: "Ow! What the…?"

A/N: So this is my new version of Digital Nexus. This I hope will be a much better story. Just letting you all know this story is being written with Google Gemini. I have had much better luck with this AI than most others. So do not complain, please. Also, I do not own Sonic the Hedgehog, Kingdom Hearts, or Hyperdimension Neptunia or any game titles or items within the series. The only things I do own are the ideas for Xoruxshy's weapons, Xoruxshy herself, the name Mobius Heart, and the idea for the Basilicom that exists in the middle of the omniverse. See you in the next chapter.
