All the students stood in rows on the concrete floor inside a large, spacious room. 

It was much bigger than our classroom—maybe four times bigger. It was open and empty and had no furniture besides the human dummies that took a stance at the far end of the room. 

The walls were thick, with layers of concrete and bricks infused with magic to increase their durability and at last, was a metal sheet painted over the bricks that gave them a vague glossy look. The ceiling probably used the same formula as it was similar in look but had flat strips of magic lights that illuminated the whole area. 

Right now we, the whole of class 1B, were in a room specifically made to practice magic. This was one of the many rooms which were located in the Mains rather than in Instrs and were similar in design.
