Smoke

The entrance to the academy had fallen. Arcadios Royal Academy's grounds were surrounded by a large wall to prevent any mishaps from escaping into the city. Spells and Arts were frequently used all around the facility and the walls were put in place to contain them within the academy and prevent any errant fireballs from heading into the city.

This meant the academy looked like a fortress on the outskirts of the capital. There was also only a single entrance on the whole of the walls and that was the one that led to the city. This entrance had fallen to the control of these unknown attackers which had cornered the students inside.
