The Pure White Tower was a very tall high tower, and besides being tall, it covered a large enough area... This might sound redundant, but it really needed to be this large to accommodate numerous mage students and schools.
However, upon actually entering the tower, one would find... the interior space of the Mage Tower was far larger than it appeared from the outside, to the extent that new apprentices couldn't help but take another look from the outside.
This was the so-called Half-plane technology... the same principle as the Half-plane Prison beneath the Demon King Castle.
In short, it could be understood as a very fantastical "spatial folding" technology, despite sounding very sci-fi.
At this moment, Yila, Vera, and Mobillas were sitting in the War Magic Department's classroom... This classroom wasn't the type one might imagine with many students sitting in rows.
To describe it, it was more like a grand library.
