As soon as Harry has crossed the threshold of the room, a light spot appears under his feet, and cheerful sparks run in all directions, illuminating the room covered in darkness. Without stopping, he passes to the middle of the small, perfectly round hall and stands waiting, giving Alrus, who has followed him, time to look around. In fact, there isn't much to see in the room, except for the single podium to the left of the door.

«Instead of my secret, I’ll present another my project that isn’t so dangerous to me, but it will be no less interesting,» answers Harry with a hand circling a room and stopping it on some strange construction.

 «I called this room the Hall of Memories, and this is,» he goes to the podium, and having raised on it, puts a hand on something a little bit resembling a computer table. «I called this a magethinker.»

Alrus gets closer at the same time, turning to the magical vision and beginning to investigate the magethinker. In several minutes, he stands still in admiration.

In general, if to discard the monitor and the horizontal surface protruding a little bit forward, the magethinker looks more like a crystal lump from which the embedded artefacts, made of various materials of different value and colour, protrude in different directions.

 What appeared before Alrus can’t be explained in simple words, for only an artefactor, a professional in his field, can really appreciate what Harry had created. Alrus can do it, and therefore, continuing to examine the masterpiece, barely audible whispers:

 «It’s amazing, father, to combine into a single whole and moreover make it work ... um, the magethinker works, doesn't it?»

«Yes, it works great.»

«So what was I talking about? Here, not everyone can make to work at once so many artefacts, both simple and complex. You're a genius! I admit, you’re right! After seeing this masterpiece, anyone will believe that this is precisely the secret that you hide.»

«Yeah, right!» Harry says cheerfully, his son's appraisal and recognition of his achievements are pleasant for him.

After examining the magethinker for a while, Alrus places his attention on the podium and the two chairs standing on it, for they aren’t as simple as they might appear at first glance.

 First of all, his attraction is drawn by the material from which they were made. The complex alloy of different types of tree species intricately intertwined with each other, creating an unusual colour pattern. The thin, barely discernible chains of runes twist all over the surface of the chairs and the podium, fitting into the pattern of the material, underlining and complementing it.

Waiting for his son to have a good look at his creation, Harry sits on the chair. With difficulty tearing him away from contemplating the artifactual wonder created by his father's genius, Alrus shifts his gaze to him and raises his left eyebrow in a mute question. His father understands him correctly; he waves his hand invitingly towards the second chair and waits until Alrus nestles seated to begin his narration.

«Let me tell you a story of a magethinker's creation from the beginning.»

After receiving a sign of agreement in the form of a nod, Harry thinks for a while bringing his thoughts into some order, and only after that does he begin to tell.

«One day, after you and I went to the movie and I listened to your dreams about the appearance of something like that with a magical component in the magical world, a picture passed through my mind of how I watch memories while sitting on a comfy couch. This vision inspired me to attempt the creation of something like this.  Properly having thought over this the idea, first of all, I began to study the thoughtdropper and simultaneously began to seek any available information about it or anything related to it.

I knew from the beginning that the way of its creation was lost, but even these small data I could find helped me understand the method of work.

The magethinker‘s work is based on the use of mental magic. At the moment of contact between the mage’s face and a thoughtdropper’s surface, a separation of a thin mental body occurs, and with its help, the mage can see the memories in the thoughtdropper.

Why the thoughtdropper was created like this and not otherwise, I found out later during complex experiments. Eventually, I learned the following information: the environment in which memories are reproduced is dangerous for the physical body of a mage.

I conducted a series of experiments from which I found out that the physical body of a simple mouse, after being in this medium, begins immediately to destroy at the cellar level, and already on the third day, a death occurs.

In a magical mouse, after being in a thoughtdropper while viewing memories, its magical essence is first destroyed for a month, and only after that does it die.

From these and a number of other experiments, I had a theory as to why the magicians of the past, having created a thoughtdropper, left everything like this. My guess is that it was for one of two reasons: either they didn't do any more research after getting the results according to the principle «it works, let’s leave it» or because they couldn't find a way to solve the problem of not harming the physical body during a viewing.»

«I think both of those variants have a right to exist,» Alrus says thoughtfully.

Harry only nods in a sign of consent, and in order not to lose the train of thought, he continues.

«And since at that point in my life I had no useful ideas to solve this problem, I decided for some time to switch to the magebook’s creation.»

The formed pause is disrupted by a loud Harry’s exclamation.

«Twinkie!»

«What does Master Harry want?»

«Water to soak my throat, light wine, and food.»

When the wish is fulfilled, he pours himself some water, drinks it, and only after this continues.

«While I was engaged in the creation of the magobook I had an idea how to solve the problem of harmful influence on the physical body,» he smiles fervently. A funny spark flashes in his green eyes, and he winks at his son.

«This platform, as well as the armchairs themselves, allows to create and hold around us a static protective field that completely neutralises the harmful influence on the organism.»

After he becomes thoughtful, he drums on the armrest.

«That's it for the preamble; let's go on to a demonstration.»

After these words, Harry runs his hand across the horizontal surface, which immediately lights up, simultaneously explaining.

« It is a universal keyboard, based on the touch keyboard, but with much more capabilities. It contains all the alphabets of the leading languages in our world, as well as all the rune alphabets I know at the moment. In addition, it has a sensory mode for the magethinker. Such a solution makes the work much easier.»

A few touches of the fingertips and there the floor ceases to shine, and the walls of the room, as well as a ceiling made in the form of  a small dome starting at a height of about two meters, begin to shimmer dimly, scattering the darkness that has appeared for a moment.

A few more strokes of the fingers and around the podium a thin film of protection appears, looking through which one may have thought that the walls have disappeared, replaced by a haze of compressed, heated air that can be observed in the desert when the sun is at its zenith.

Ree enchantedly gazes at the haze and recollects himself only when the haze is replaced by a picture of memory.
