A door reveals itself, separating the atmosphere of two worlds. On one side, darkness, but on the other, as you pass through the frame that holds it, a pink light greets cordially, while its warm glow, which induces sleep, shows the immediate vicinity of the place.

A room is observed that, on both sides, has in its interior two enormous stone tanks, which measure at least one meter high, and extend along the entire site, starting from the wall where the entrance is located until colliding against its distant opposite.

Both constructions are perfectly homologous to each other, except for one thing that differentiates them.

The one on the right is covered with a lid composed of the same rough material, one to which innumerable holes as thick as a finger have been made. Meanwhile, the one on the left, being completely uncovered, allows the curious eye to look inside.

In one, it is unknown what it contains because the holes on it are too small to allow light to pass through. In the other one, by contrast, the tenants that inhabit it are easily visible.

More than a dozen babies who, indifferent to the uncomfortable positions in which they lie, sleep peacefully as they ignore the noise coming from beyond a musty wooden door.

This site, which differs from the other several rooms inside the cave, is divided into two sections. The first is this one, where the babies rest comfortably, surrounded by a warm and cozy atmosphere. However, it is only after advancing to the next part that the true face of the place is revealed.

As they changed location, the pink light was replaced by a damp and disturbing shade of crimson, which covered and embraced all the surrounding objects as if this was a liquid.

Ignoring the above, the first difference to notice would be the size of the place, as this is distinctly larger than the previous section. In addition, when looking in a little more detail, again on the sides, as if they were intentionally replacing the stone tanks, are located numerous shelves and bookcases.

On the right are bookcases filled with books, both new and antique. In addition, on the floor beneath them, countless sheets of paper, stained with various substances, are lying around.

On the left, the shelves are loaded with materials of all sizes, shapes, colors, and even smells, from claws, teeth, organs, and eyes to other body parts of unrecognizable appearances.

This entire room, or at least half of it, undoubtedly shares similarities between a laboratory and an office. Such a relationship is even more marked when considering that, in the center of the place, there is an old wooden table, one on which there is a plate with food, meat is what it contains, and next to that, an empty crystal cup.

In addition, next to the table, there is also a chair, which is unoccupied, as the only person who could use it is currently standing.

Looking to the front, the old man from before is seen, still wearing the same luxurious garments with the crown slipping down to the side of his head.

He, on his feet, while the weight of his body leans in the direction of his only functional leg, directs his gaze towards a pool filled to the brim with blood, located a few meters away from him, which until recently was bubbling.

Seeing that all movement had stopped inside, and after incorporating adequately, the old man, at a slow pace to which he is accustomed, walked towards the stone slab located next to the pool, which simulates a table, where upon arrival, he placed the tools held in his wrinkled hands, making the liquid that until now was dripping around the edges of this, increase considerably, staining the dirt floor even more with its color.

After that, he advanced to the center of the room, where, after sitting in the chair that awaited his arrival and without even cleaning his hands, he began to eat his dinner,

Incredible, surprising, and at the same time aberrant. The man, not caring about the peculiar aroma that wafted everywhere, tasted his food with great tranquility, even stopping at times to enjoy the flavor that ran through his mouth.

Such a disgusting act went on for a long time since the old man, not possessing sufficient strength in his jaw, found it difficult to cut the meat with his teeth, so he needed to drink water with each gulp from the cup he was constantly filling.

Chew, chew, swallow, and slurp, those, along with the ceaseless dripping, were the only sounds that could be heard in the room.

An oppressive environment.

However, that was broken when, from that place where all movement had ceased, new signs of life appeared. The blood in the pool was sloshing and bubbling with force again.

This event greatly surprised the old man, who, dropping the cutlery he held in his hands, stood up as fast as his decrepit body would allow him, to approach the side of the pool.

Now, unlike before, with a twinkle in his eye and a frown on his face, he waited patiently for the struggles of that being to stop again so that he could finally know the result of the experiment.
