I'm actually surprised at how this turned out. I was expecting total garbage quality, but I think I did this image some justice.
MLP and Terraria crossover with Aria at full power, casting the Nebula Arcanum spell during the final fight.
_Aria picked up the strange, mystic orb. It looked like a led sphere, but shone and sparkled like the universe itself. It was nearly weightless, and glowed brighter in reaction to Aria's magic.
She looked it over before a dark, foreboding voice pierced her mind and spoke to her.
"Miss Blaze. Do you feel it, the dark magic contained within the Arcanum? Release it. Absorb the artifact and let its ancient powers course through your veins."
Aria looks down at her now clenched right fist. Could she really do it? Could she absorb this artifact's power like the rest and contain what seemingly boundless energy the orb had?
"You always had the power to wield such a tool… You needed only the key to awaken it."
She released the orb as it floated in front of her slowly. Closing her eyes, she put her hands around the Arcanum orb and began to siphon the power. Within a few seconds, the ancient artifact was no more, and the land around her grew dark once again.
Had she done it? Was it… That simple to house and contain such power?
With a sudden jolt, her body was levitated into the air. Her eyes shot wide as they began to illuminate with a bright red light. Her hands flared with the same glow as she fought to control the power that sparked and zipped through her body.
Being gently set back on the ground, Aria blinked a few times. She could see just as normal… But she also felt the ancient siren magic coursing through her once more—This time without the need of her voice. Clenching and opening her hands, she observed the flow of magic emanating from her fists. Her mind once more was pierced by the same voice.
"Do you feel it? That ancient power in your body? Concentrate. Draw upon its strength—Draw upon your strength. Let it loose. Feel the power to tear apart worlds!"
Closing her eyes, she dug deep for the power. Tapping into it, she opened her eyes and thrust her left hand out, expelling a magical blast.
"FWOOSH~"
A dark purple ball of energy with a light pink center and swirls rushed out of her hand and toward the ground. It looked and felt like a black hole, but it did not act like a vacuum. As it collided with the ground, it created a great tear in the earth, ripping it apart violently.
"This ancient power… The Nebula Arcanum… This is exactly the kind of power I had been itching for. With this, nothing can stop me!" Aria cackled with a cracked, power obsessed laugh._
