Academy of Magic

You're sitting in a park in your home world and suddenly feel nauseous. The next moment, you feel a sudden pull.
When you feel a little better, your first thought is that you're in the hospital. But your surroundings don't confirm this thought.
You're in a wood-paneled room. The floor and ceiling are stone. Against the wall opposite you is a stone fireplace, clearly functional and not merely decorative. A fire is currently burning in it. You're sitting in a leather chair. A heavy wooden table stands to your side.
"Here, drink this, you'll feel better, " a male voice said, handing you an iron goblet. You instinctively take the goblet and sample the liquid inside. It tastes cool and sour.
Where am I? You ask, looking at the man who handed you the cup. He's quite tall, about six feet tall, with a strong build. It's clear he doesn't just sit at his desk. He looks about forty-five. His face is strong, with fine wrinkles around his eyes. His eyes are gray, tenacious, and appraising. But you can see weariness in them.
You are in the royal castle of Novograd, the capital of Ostia. A man is looking at you intently. Right now, you are in my office.
You're starting to think talk show hosts have gone completely nuts. They're now picking random people off the street and throwing them into the thick of things.
What about you? You decide to join the game by inspecting the premises for hidden cameras.
My apologies. I completely forgot to introduce myself. Archmage Lysander. The man nodded slightly.
Okay, Mr. Lysander. You're in favor of the game. Tell me, what am I doing in a castle in a city I don't know?
There is magic and magicians in our world , the man began to explain. You listened attentively. I wondered what the talk show would be like. But unfortunately, the locals' abilities weaken with each new generation. The man turned to the fireplace, looking at the flames. Therefore, a spell was created that summons new people into our world who have the potential to learn magic.
