Sylvester didn't need to move too fast. After the recent change in his body, he was more in tune with the magical energies than a Solarium Crystal. It was as if he breathed magic itself.
So, as he walked towards the main deck where all the chaos was likely happening, he used Electromagnetic Manipulation and Metal Manipulation to mend the broken airship and slow its descent to the ground.
By then, Dalgan was able to manage the crowd as well, since the airship wasn't descending that fast anymore. The pilots were able to steer at the same time and bring the large vehicle to a slow descent over the treeline.
"We're leaving." Sylvester gathered the four and led them away from the crowd. "We'll continue moving towards your home, Dalgan."
Crack!
