The fight raged on between Sapph and Obsidian, the two having started to exchange blows with their fists long ago. Though Obsidian had the advantage of aura, Sapph managed to stun him a moment, something he was about to take advantage of. He grabbed Obsidian's head with both hands and jumped, holding himself up in a handstand. "Now I END THIS!" With that, he spun, twisting Obsidian's head around to face behind him with a sickening SNAP, after which he let himself fall, slamming his knees into the other knight's back to knock him to the ground.
Sapph panted heavily, grabbing his sword back from the ground and looking at Obsidian. "Immortal my ass. You were probably just some wannabe follower of his." He said, still panting. He turned and started walking back into town.
"You think so?"
Sapph froze. Did Obsidian just say that? No, impossible. His neck was twisted 180 degrees. He quickly turned around to see none other than Obsidian, back on his feet, but his head was still twisted around.
Obsidian slowly brought his hands up to his own head and twisted it right back into it's proper position, the sounds of snapping bones being heard again. "I told you, I'm immortal."
Sapph was too stunned by what he just witnessed to notice Hierophant and Pyro arriving, nor Obsidian picking his sword back up and stabbing it straight through Sapph's chest. "Though, I suppose you won't be around long enough to comprehend that." Obsidian said, twisting his sword before removing it from Sapph and blasting the wound with a blast of aura, slamming Sapph into a tree. With that, Obsidian faded from sight, laughing maniacally as he did.
(And don't worry, I has a plan.)
