"Care to explain why that's bad?" Corvinus inquired, interested to see how Zephyr would respond.
Zephyr flipped the grill, thinking for a second before continuing.
"All things in nature fall to the ground. The same goes for a spell that is out of the mage's control."
He pointed at the roof.
"The roof was completed last. She formed it, and her attention was still on it when she relinquished her control and turned it into solid."
Zephyr was very sensitive to mana. He could clearly sense the way it flowed when it was outside of a mage's body.
"Thus, the roof began to solidify first, and the pillar supporting it solidified a beat later."
Corvinus nodded as Zephyr explained.
"If she were building a larger construct, the roof would have been too heavy for the softer base to support, and it would have collapsed. Fortunately, the rate at which the stone hardened was quick." Zephyr added as a finishing touch.
