Otherworld TRPG Game Master

I became a wizard of the Illusion Magic School and decided to create a virtual reality with illusion magic to play a tabletop role-playing game (TRPG).
It was great to create a virtual reality, but I was in trouble because there were no suitable players. During that time, I received an offer to be the professor from the Royal Academy.
The offer was to use illusion magic to fill the students’ lack of practical experience safely. And so, I became a professor at the academy.
“Send me back, send me back to that world right now-!”
“Outer god, someday an outer god will be our doom, we’ll all die!!”
“I am not the bastard of the Redburn Ducal Family. I am the foremost disciple of the Great Namgung Clan, Namgung Qinghui!”
But it seems there is a bit of a misunderstanding.
This isn’t a spell for dimensional travel, kids. It’s fiction…
