Vulcan joined the fight when Wayvern was knocked out by one of Oren's shadow blasts. Wayvern was only conscious for long enough to see Babylon be summoned by Dante and Vulcan. Then he slipped into the darkness. He was falling slowly. The ground he eventually reached was a circle of stained glass. The image in it was Rainbow Dash, primarily, just in front of Cloudsdale. But there were other faces in the glass. Wayvern stood up and realized he was still a hunter. He looked at the glass and saw his reflection; his hair was spiky and had a windswept look to it. His duster coat looked as blue as his equestrian body. Two straps went across his torso downwards from each shoulder. He always felt something heavy on the small of his back, which was probably the Magnet used to hold Hummingbird in place.
"What is this?" Wayvern said. He didn't expect an answer, but that's what he got from the depths of his mind.
This is… the Abysmal Trials, it said. You have… a greater power… within you… it's time you gave it shape. Three lights shined through the Darkness and came closer to the ground that Wayvern was standing on they changed shape to a Pegasus wing, a pony hoof, and a Unicorn's horn. Wayvern stepped in the middle of these three appendages and waited for instruction. You must decide… what drives… your power. The voice said. The Power of the Winged… the Power of the Magical… or the Power of the Steady.
Wayvern walked up to the wing. The Power of the Winged… incredible speed, a razor feather that could slice a mountain… is this what guides you? Wayvern thought about it… but decided that it wasn't right. He went to the horn. The power of the Magical… immeasurable wisdom, bones that could move without touch…is this what drives you? Again, Wayvern felt wrong and just walked away. The Power of the Steady… strong will, a body fit to aid the weak… is this what you choose? None of the answers were right for him. He couldn't choose just one as his motivation. Finally he stepped back into the middle of the glass and announced:
"I can't choose my one motivation!"
It is over… the voice said. Wayvern expected that he failed. But the voice said something beyond that. You passed the challenge… as a trophy… your power… Apocalypse. The three dream pieces faded and in the place of the wing was a sword with two single edge blades and a spike all on one hilt. It was made of a black metal, and the leather had a silvery glow to it. Wayvern walked over to the sword and reluctantly grabbed it by the hilt. A bright light flashed and he woke up in his room back in Canterlot.
