87 Ch 87: Answer

A restoration specialist was called to Grand Tutor Saile's residence.

Restoration specialists were wizards with auxiliary-type innate arcane techniques that could be used for restoring old or damaged buildings to their original condition.

The restoration specialist was tasked with repairing Grand Tutor Saile's residence to its original state.

With a single movement of his hand, the debris on the ground rose and reassembled into the east wing of the residence. He moved his hand a few more times, removing every damage caused by the explosion from the surroundings. 

In mere moments, Grand Tutor Saile's residence was back to its grandiose state before the explosion!

Later that night, inside the residence of Grand Tutor Saile, in a room lavishly decorated with the fine work of artists from across Serphendale.

The room was gently illuminated by the light cast by orbs on two stands placed near the wall under a majestic painting.
