Black.
That was all that Zazel could see, from the endless sky to the bottomless bellows below. Skeletons of varying sizes waiting in line, watching the judge with extreme focus and attentiveness, never budging an inch. The Judge in this realm looked like a demon in red with a traditional imperial robe and a headpiece that acts as their star, the jewelry fashioned in the middle gleaming down, an eye out of royalty. The Prince would be perplexed at how Harvard even possessed such a monster like this originally, wondering what exactly was this place used for before they met, exploring his surroundings as quick as possible. He could hear groans and moans from above, zombies raining down and trying to reach for the demon with the tendency to kill. The Demon was quick in setting up a sigil, Sabnock, to create his trusty M72 LAW, Firing the rocket in the farthest reach possible. In conjunction, he'd cast Asmodeus, creating the infernal dragon and have its tail swat the boy away, allowing him to reach and ride the rocket, waving goodbye to the undead as he took off. As he did, however, he would begin to listen to a song. A hypnotic tune that would nearly had him fall off of the rocket in order to follow its sound.
A Violin.
KRASH!!!
More of the undead arrived, some throwing each other over at the Demon's direction in order to intercept and force the rocket to explode, prompting Zazel to push it up in order to evade the monstrous corpses, weaving it around the environment, aiming at a massive cluster and hopping off as he creates another Sigil.
KA-BOOOOM!!!!
A mighty explosion that would push the Prince back down to the landscape, seeing more skeletons appear to await their judgement, a few humans walking in a straight line to ensure the dead remained in their proper line, ones with the same garments but with no crown visible, only a ring that indicates the number of the individual, assuming it was of proper ranking. Such deceased figures would act as his perfect disguise away from the dead, as he'd set up Kimaris and let the Sigil crack. "Armor Magic: Goetia...!" He'd state, letting the monster envelop him, donning him in the same set of robes as the Judge that watches over the dead, a set of chain mail underneath it, binding itself in tandem with the cloth to make it as fluid as possible, while also being just as sturdy. As he took on the robes, however, his skin began to rot away, slowly turning him into the very skeletons that walked by his side. Such an effect is intended, as it was the main property for the necrotic Goetia. Furthermore, as he could see the swarm of zombies rushing in, more bodies down from the black sky, trying to find what they would perceive to be fresh meat, they would not be able to find Zazel. His body has become just as much a corpse as them, after all, used and rotten, his eye sockets tilting around in the same direction as his regular eyes were, watching them try to cut in line and reach for the King, much to no avail.
He is no different than the dead now.
The demon would make his way around the environment, listening in to the Violin's song, a tune that he could recall faintly during his youth in Hell. A musician that was rumored to ally itself with a human, teaching them the most beautiful piece in the world, laughing away as he'd see him try to mimic what it has made. He can recall his mothers rolling their eyes as the musician gloated, with him pondering why was he so happy. He smiled as he'd remember hearing one of them, Agratt, making a joke at how he was bragging at being a teacher, as if such a skill was ever needed. "Good times... Though, Who's playing that now? It has to be Jesta, right? How is his music audible even here...?" He'd ask, wondering more about how the structure of Rubix was made. Once he reached to a tangible object, a sword from a discarded warrior, he'd quickly touch it and would be transported elsewhere, now in a Feudal Era-style temple filled to the brim with corpses, the sun now donning a frowning face instead of its usual smiling one. He would be able to deduce that whatever Rubix was, is a beast with endless realms that intersected with one of them, all of which has something to do. Skeletons, Zombies, and what he could assume would be Shoguns and Samurai fending off the deceased spirits.
This must've been Harvard's personal playground before meeting him as a whole.
As he wandered across the roof, he could hear the tune getting louder. He was getting closer. One at a time, he touched a random object. No matter what it was, it would take him to a random place, inevitably sending him to the source of the sound, alongside with Harvard. "Oh! There you are! Same run-in?" He'd ask as he'd try to catch up with the Card Magician, his curiosity wandering as he looked around the new room he was in.
"Mhm. Stolas and Solomon should be here soon, hopefully..." Harvard replied, prompting Zazel to tilt his head.
"So, what's the lesson in Heroism now, dude?"
"D'ah- You were actually listening to what I was saying??"
"Well, yeah! We've been together for a while, and you did offer some good points."
Harvard would be a bit stunned as he'd slow himself, waiting just outside the source for the song, pondering what would a Hero do in this situation. "Well ah....Hmm... I guess we just try to beat up the bad guy as much as possible? Making sure they don't escape? Pressure stuff!"
Zazel would chuckle a bit as he'd hear his makeshift wisdom. "A'ight. Good to know. I'll keep that in mind, Teach!" He'd joke, looking to his side to see if the others are arriving.
