Chaos ensued in the tower. Some tried to flee only to be struck down from behind. The ones that reached the walls of flame despaired as they realized there was no hope of exit. The desperate even tossed themselves into the flames willingly to go out on their own terms than be slaughtered like animals. It was one of the biggest events of mass hysteria Caius had witnessed in his life. This is why he harshly judged Yumi for her activities. With no other choice, he gathered up some black sky god slayer magic and lifted himself off the ground. Flying in the sky, he would have a birds eye view of the battle and would be out of harm's reach to anyone without a ranged attack. Caius put his hands together and slowly pulled them away to form a ball of wind. He then closed his hands to detonate the ball causing a mass vortex that would fill up the entire volume of the tower. Anyone caught inside would be torn to shreds by the violent winds. After the attack had completed, the winds cleared to show blood and sinew of his former opponents sprawled across the ground. All had been defeated. All but one.
Caius looked on as a man held a giant two handed sword using a light around his body to protect himself from the attack. Caius raised his hand to prepare another attack but this time the man with the sword would retaliate. In a blinding flash, a crescent of light would fire out when he swung his sword. Caius fired a blast of sky god slayer magic in response. The two spells collided but the light overtook the darkness. With his attack shattered, Caius was struck by the attack and struck across the chest and stomach along the scar that he had received from the Blue Pegasus mage. It was deja vu. Caius was struck down from the sky and fell spine first into the rock hard ground. Before he could lift himself up, the sword mage was upon him with the sword lifted up behind his head to deliver the final blow. As the blade rang down, Caius would use one of his secret techniques. It was one only Grimoire Heart's Spymaster could use. His body would turn into a flurry of mana that would position him behind the mana. The sword struck down but Caius would be nowhere to be found. A blade of black wind would extend from Caius’ hand and pierce the man's heart before he could respond. The madness was finally over and he was the last one standing
The walls of green flame slowly came down as the tower returned to normal. The green seal on the ground remained as it turned brighter than before. The blood of the dead was seeping into the seal making it stronger. Caius could sense its energy rapidly growing. The old man stepped down from the podium and approached Caius.
"Bravo. You have managed to....." His words were cut off. Caius held his hand out and had fired a blast of wind through the frail man's chest. He was sick of his rambling. This whole ordeal had been a waste of time. Caius slowly got up to his two feet and started to stumble out to the door. He needed medical attention from the guild.
A shiver ran down Caius' spine as he felt a presence appear behind him. This dark and sinister aura was one he felt before. It was like Yumi's but on a whole other level His vision would start to blur and his body would start to tremble at this superior entity. This was something he couldn't escape. Hesitantly, he turned around to see what was the source of this evil. The old man was standing up despite the hole being blown into this chest from earlier. The body had green cracks in it as the skins started to shed. Two dark wings sprouted from his back and horns protruding from his skull. His body started to gather green markings that covered his whole body. It was a true demon. Before he could speak, the demon grabbed Caius by the throat with his claws.
"The truth is it requires all 50 of you to open up a portal back home. There is no power for you here I just enjoy tormenting you humans for entertainment . Now it's time to die." The horned devil would say.
"Wait......" Caius would struggled out
"Oh are you going to beg for your life." the demon chuckled. He loosened his grip on his throat to allow him to speak easier almost to hear the last request.
"I've seen it done before. Make me a demon like you...."" Caius said with the last of his breath. It was the only thing he could think of at a time like this to save himself. He was afraid of death. There was so much he needed to accomplish. Yumi had traded her human body for a demon one. Not only did she regain her youth but also rose a rank in power. In order to preserve himself. He would become what he hated.
The demon cackled like a madman at his request.
"In my hundreds of years. I have never seen one ask to intentionally become one of us. Judging by your smell I see you have interacted with demons in the past. Very well. I will use your human body as the last tribute. In return, I'll grant you the demon vessel you seek. That is if you can survive the transformation" The demon's hand would glow green as fire would fill up Caius body. The searing pain filled his body as his skin would start to crack off his body. A loud wail of agony escaped Caius before the demon pushed his wings together and caused his body to explode into a viridian inferno. It was almost like a dream. Caius felt himself floating in darkness. He didn't know if he was dead or alive but it was peaceful.
When he awoke, he was on the ground of the mage tower. He sat up to see the demon was gone. The entire tower was spotless as if nothing happened. His body felt different from before. He could no longer feel the wind around him. He tried to summon his god slayer magic but nothing came. Instead, a shock wave of magic left his body that struck out in all directions. The mage tower stone was obliterated in an instant and turned to dust at the mighty magic power. When his eyes opened, a giant crater was all that was left. Caius looked at his hands and started to shake at this marvelous power. He had survived the transformation and had become a full fledged demon. With this, he would become invincible.
OOC: Caius is now a demon :)
