Hearing the monster's request, Ba'al shuddered. "How would that work? Aren't you already attached to that guy?"
[Not entirely. Approach and I will inhabit you.] The crooked gaze of the creature fixed on Ba'al, the empty eyes leering.
As Ba'al considered what to do, the monster took a step forward. "Uh, what exactly are you, to begin with? And who is your Lord?"
[My Lord is the guardian of rest, the Lord of the silenced, Volkov the Undertaker.] Ba'al took a step back just as the creature lunged for him.
'Slow.' Ba'al thought right before a beam of darkness closed the small distance and jabbed right through his thigh. "Ah!" Ba'al cried out as he jumped back and grabbed onto the wound. Between his fingers, blood was flowing. He looked up just as another beam shot out. Ducking to his right, Ba'al called out, "That's foul, you know! We were having a nice conversation and you ruined it!"
[I had no reason to believe that you would comply with me. I merely took preemptive measures to assure that I would have a better host.] The darkness swirled around its hand, separating into three small spheres.
"Since you started it, I might as well finish it." Ba'al ran light magic through his leg, causing the wound to start closing. As soon as the bleeding was stopped, Ba'al launched himself behind one of the stone gateways at the entrance to the greenway. A ball of darkness shot out and cut right through the stone, grazing his shoulder.
[You have no way to defeat me, Human. An existence at your level cannot comprehend what is needed in order to destroy a Revenant such as I.]
"Yeah, well, I might not be able to destroy you, but I will sure as hell go down trying." Ba'al flipped himself around, diving out of the way of another tendril of darkness and rushing in to attack the Revenant.
[Fool, physical attacks will do you little good, this host contains no essence of mine, he is but a puppet used to conduct my energy.] The Revenant cackled as it witnessed Ba'al's approach.
'Lets hope this works. I have no clue what will happen if I try this, yolo I guess.' Ba'al was pierced through the stomach as he finally reached the Revenant. Coughing up a mouthful of blood, he grabbed the nail and yanked it out.
As soon as the nail was removed, the corpse of the dimwitted student collapsed as Ba'al fell onto his butt, tendrils of darkness piercing into his arm and working their way up towards his shoulder. [Ah, yes, a direct path to the brain, you've made my work easy child. Now sit back and sink into eternal sleep.]
"No, how about you." Ba'al stuttered out his response as he gathered all of his remaining mana into his core, breaking it down to surpass his limits. As the core dissolved, his mana migrated to another place within his body, one he was unfamiliar with.
[No! Stop this foolishness. If you burst your Holy Root of Akasha then you will be left with nothing but certain death! Stop this RIGHT NOW!] The Revenant's voice within Ba'al's head grew frantic as the mana finished repositioning itself. [An Unclassified such as you will have no other fate than death! Stop this madness! The explosion itself will level this city, if not more. Don't you care about those other humans?]
'Warning, your Akashic Root is straining under the pressure of mana. It is recommended that you cease these actions at once.' As Ba'al was finishing his preparations, he received around a dozen such notifications, although he ignored them all.
"It's either you or me, Revenant!" Ba'al channeled all the mana he built up into his biggest spell yet and targeted it at himself. "Plague of Darkness!" The dark mana ran rampant through his body, tearing through the tendrils of the Revenant and the nail itself who, having lost a host, lost most of their power.
[You filthy inferior! How dare you do this to me! I swear as Vassal of Lord Volkov the Undertaker, you will meet with a thousand deaths before you are allowed eternal rest. You shall know no peace in this life nor the next Ba'al Callisto!] As the Revenant's nail crumbled, Ba'al fell completely back, his energy spent.
