Here we go, into the pit.
Andrew continued laughing as darkness surrounded him. "You think you've found an ally in darkness." he hissed, "Do you comprehend the power you were gifted with? The same power I was born into." Andrew turned, his eyes blood red.
"Those eyes." Matt gasped.
"Where do you think the shadows all go in order to hide from the precious light? Just who do you think faces them?" a scythe materialized in the advancing boy's hand.
"That voice." Matt began backing away.
Andrew held the blade out in front of him. "What you posses is a mere fraction of their power. The same power I stand unyielding against, each and every night."
"Stay back!" Matt demanded, sending his blades after his brother.
Andrew swiped his scythe and easily deflected them. "You are nothing compared to the darkness." he declared, the darkness spreading. "You are nothing compared to me!" Matt found himself pinned between the wall and the blade. "You think you know fear?" Andrew shouted. "I'll show you true terror!"
"What...are you?" Matt asked, clearly terrified.
Andrew laughed, raising the scythe for the final blow. "I... am the KON." Andrew swung and then, darkness.
...
The pack began to stir. Twilight rubbed her head and sat up as the events of the last few hours came back to her. "Andrew!" she called, looking around franticly.
"Good, your up." Twi looked to see Andrew sitting just behind her. "It's done." he said as she opened her mouth.
"That couldn't have been easy for you." Twilight said, moving to sit by him.
"It wasn't, but he's back in Tarturus, and this time he won't come back." Andrew brushed the girl's purple hair out of her eyes. "I'm just glad you and the others are safe." Twilight blushed at the Wolf-Falcon's touch, but didn't shy away. "Twilight, I should tell Celestia and Discord. Can you watch them?" he asked, pointing to the still unconscious pack members. Twilight nodded and Andrew ran off.
I know, it's a short one. The idea for the KON scene was inspired by Fall of the Crystal Empire.
