For the time being, I took the book out of my luggage and looked at it while making a comparison.
It had a resemblance to the type of magic circles which are capable of two-way teleportation.
The details are different, but there's no mistake on the characteristics.
If the story I heard from Nanahoshi is true, then if you place your foot here, just like that, you'll be in Begaritto Continent.
Elinalise just kept staring at the teleport magic circle while standing still.
