Everything before Grimm's eyes turned dark for a moment and the next second he had arrived at a completely new place.
The place was lit brightly by warm, sorcery lights. Elements in the air flew in order. The clean floor was made of blocks of slates with innumerable signs hovering off them. It formed a circle matrix with six stars in it and Grimm was standing on the very center of the matrix.
"Where am I?" Grimm wondered.
"You're good to hang in there for over two hours. What did you get out there?" A familiar voice came up.
Grimm turned back and traced the voice. It was his master sorcerer Peranos. And amazingly enough, he found himself standing on the 30-meter-long-in-diameter, circular disk of a high tower.
"Master, where is this place?" Grimm looked down.
"The 99th floor of the Black Tower." Peranos smiled. "The mirror is quite different from the sorcerer world, isn't it? I've been there a couple of times, and that place's never failed me."
