The observer, a damned creature borne from the depths of the abyss surrounding the chained city, it was now standing a few meters in front of a couple of tiny, insignificant humans.

Yes, they couldn't be anything else but critters, them, as well as all the other students staring at its magnificent black, bulb-shaped, sticky self. Of course, it couldn't know that its entire existence had been transitioned to that of a toy, for a mere educational purpose.

Even if the army of the Abyss was not as crude and primitive as one would assume, their bottomless hunger for destruction had always been their primary objective.

Thus, even if it could recognize Dominus Karl as one of the Lords under the council, it couldn't understand why the deranged soul master had not yet killed it.

Soon enough, it felt a strong pull resonating from its very soul. The call of the Abyss was upon the Observer, and it would respond to their dark master.

The long tentacles of the observer, which previously hang from its body aimlessly, were now undulating up and down, and many dark circles of runes encompassed them. Black droplets of fluid were thus thrown in random directions, about to hit whoever was unlucky enough.

A horrid expression plastered the faces of the students seated in the first rows of the classroom. Even then, there was no fear in the young hatchlings of the council. Simple disgust clouded their minds, the thought of the horrible liquid touching their clean self, was more kin to a primordial instinct than anything.

A premonition quickly realized in Nestor's mind, and he desperately jumped and rolled on the ground, behind the teacher's desk. An intuition that soon enough found its credibility, for a split second Teresa stood in a daze, the dazzling smile plastered on her father's wrinkled face told her tales about what was to happen soon enough.

She knew she was too late, Dominus Karl was an old monster more ancient than all the presents put together. Having him as a teacher was both a blessing and a curse at the same time. But Teresa knew that this damned city was about the same. It took as much as it gave.

' Not under my watch old man! '

She suddenly rushed and jumped high up and from her right hand a small, oval-shaped mirror appeared, much like a soul artifact. Everything happened very quickly, as the smooth surface of the mirror expanded, it managed to cover the entirety of the right wing of the class, deflecting the volley of black tears.

A pained grunt, however, was soon to follow, as Teresa herself didn't quite manage to hide the entirety of her body. An ominous, sizzling sound preceded that of many others. The black liquid literally boiled on touch with her unprotected ankle, it deeply corroded her flesh, digging till her bones were for everyone to see. Soon necrosis spread around the site of impact, quickly killing the near tissues.

Not ever before had Nestor seen such a disease or venom for that. Still, from what it seemed, it wasn't expanding as much, only covering a few centimeters in radius.

' Yet she was hit by a single drop, I can't imagine how painful it would be if hit by a multitude.'

To answer, his curiosity, were the students sitting on the left row. Among them, Nestor recognized the likes of Frank, Marco, and Green who reacted much sooner than the others, and without room for politeness had jumped on top of the nearby desk, quickly running away as fast as they could.

Pained screams echoed through the walls of the room. One curious girl, with blond hair and a soft visage, had been otherwise enthralled by Professor Karl's speech, deeply interested in this particular individual, she was now screaming out of her lungs. Increadule at her bony white hand, mad terror engulfed her entire being, she couldn't believe it.

The real monster must have been the crazy professor, and certainly not the poor creature he just freed from its cage, right? Curse his stupid teachings, were they even real in the first place? Was this really such a terrifying creature?

Even in her home world, there were many animals capable of badly hurting human beings, many were much more deadly than the one in front of her.

She was furious, that's what she was, and as she was about to lash at their teacher, transforming the angst brought by the injustice that befell her, everything went black. Her thoughts were slow, messy, and unorganized.

Then, she was no more.

A dark bolt of soul energy had smitten to death the young girl, her charred corpse was now lying on the shoulder of a nearby student, a young male teen with purple hair sported a bowl cut and a tight futuristic black uniform.

"Urgh! How could you be so dense, I noticed the power fluctuations ages ago. Get off me now, you lowly one."

With contempt, he tossed the charred corpse onto the opposite student, apparently a girl, as she let out a piercing screech.

Nestor witnessed it all from behind the glass desk in the center of the room's elevated platform. He saw the huge eye of the Observer circling around its orbit with joy, as every hint of pain and desperation directly fueled the meaning of its very existence.

But then, pain assaulted even it. Nestor had come out and started slashing down at its tentacles, a bright orange halo of decay coated his rusted Khopesh.

However, a quick glance at the smiling monster at the back of the class was enough to remind it why it was in such a place, to begin with.

It had been captured not much after it was borne, as it was trying to find its rightful place among the army of the Abyss. The enemy was too powerful to even compare, as soon as the spiteful human put its sight on it, the newborn observer already lost control of its body.

All it remained for it to d was wreak havoc and damnation among these fresh hatchlings of light, for this was its purpose.

The fiend seemed more preoccupied with Mr. Dominus's presence than the little damage Nestore had been able to inflict upon it. The creature's limbs, in fact, proved to be much tougher than what he imagined at first sight. Its skin was thick and slimy, rendering useless his rusted blade, that without augmentation wouldn't be able to leave almost a scratch.

As he finally managed to cut deep and detach the creature's greater tentacles, black blood slowly oozed out of the fresh wound. Nestor's intuition kicked in and a black bolt surged in, missing its target entirely.

"Big guy, you must have felt that one huh?"

Maybe slightly corrupted by Marco's cheerful attitude, Nestor teased the abyssal creature, hoping that soul language worked for it as well.

'Mr. Domino talked to it earlier, didn't he? I'm not crazy for expecting a massive eye of doom to understand me right?

Well, that thing would be more interested in frying me up than anything else anyway.'

Armed with his trusted sword, Nestor charged once again toward the enraged floating eye, he quickly sidestepped, dodging a black tentacle coming his way, and a couple of black tears corroded his arms.

Nestor clenched his teeth and jumped onto the creature without looking back. He poured all his remaining soul energy, charging the angry Khopesh to a deeper shade of orange, bordering on red. Yet his reserves were starting to deplete much sooner than he had hoped. Today's training still weighed on his shoulders and couldn't be bridged by a few hours of rest.

Nonetheless, his blade found a target within the giant eye of the observer, which composed about seventy percent of the monster's body.

It was still, much harder than it looked, it definitely wasn't as per with a human, if not for the thick augmentation, Nestor doubted he would have managed to pierce more than a few centimeters into the eye.

Only a few droplets of dark blood threatened Nestor's well-being, as near the impaled sword, the eye started to wither in patches of dead gray tissue.

The elation brought by his short victory did not last long, as new runes circled around the angry eye, that seething with fury summoned a black pool of darkness just below Nestor.

This time, however, his intuition failed to preemptively warn him, as a black misshapen humanoid figure jumped out of the darkness and snatched the still-hanging Nestor off the observer's body.

Trying to resist with all his remaining strength, Nestor received a new premonition. It was yet, not from his newly acquired sixth sense, but his gut instinct, telling him not to get drowned in the dark portal, or else...
