The place where Saleen and the team were resting was in fact a pathway in the magic tower, and there was a staircase leading to the next story between two doors. Even if the magic array on the ground floor had been broken, the path to the next level would not be fully opened yet. It was possible that there would be another magic array waiting for them just beyond the staircase. However, that flight of stairs would have only been used by disciples. The Grade 10 mage would have most likely used a personal staircase or a transportation array.
This type of magic tower with a double layered structure was unusually strong. The walls were at least three meters thick, and even a magic trebuchet might not have been able to destroy it.
