Arcania, a great empire that prizes knowledge above all else.

I am the Tower Master. Furthermore, I am the youngest to ever ascend to this position.

When it came to magic, I lacked for nothing. I mastered spells faster than anyone, solved dilemmas that no one else could crack, and had reached a point where I felt bored with everything because there were no new challenges left.

Then one day, while deciphering ancient summoning grimoires, I discovered a peculiar magical formula capable of summoning a being possessing knowledge and concepts that do not exist in this world. The book was worn and tattered, but I knew I could figure it out quickly with some research.

For the first time in a long while, my eyes sparkled as I immersed myself in study. After about a month of research, I obtained the complete equation. Of course, the reverse calculation was impossible, meaning I couldn't send the summoned subject back, but I didn't care. I could just feed them and house them in exchange for the knowledge they would provide.

As soon as the formula was finished, I drew a summoning circle on the floor, cleared my throat, focused, and attempted the summoning.

And what appeared from the magic circle was—

Not a member of another race, nor a mage, nor a knight, nor a noble, but a man in unfamiliar attire.

After staring at him for a moment, a smile naturally formed on my lips.

Finally, something interesting has appeared.
