"Shit! They're closing the gate to the outer rim of the city!" Aohdei shouted over the whistling of the wind and the screams of people scrambling out of the way of the horse. He turned back to Rylzyr, and said more quietly, "Brace yourself, close your eyes and stop breathing for the next thirty seconds."
As they rapidly approached the great wooden gate, it's heavy oaken doors swinging ever closer together, Aohdei stretched out on of his hands, and began to concentrate. Over the last week or two he hadn't used his powers at all, but had been eating regularly, at least for him, and his, unique, diet provided him a power source if stored for long periods of time. He called upon that now, and a small ball of lava like flame began to form in his palm and rapidly expanded to the size of a small melon, now dripping superheated liquid and ashes onto the pavement and several others nearby. Flinging his arm like a whip he launched the lava ball at the gate as it closed shut, creating a small explosion and melting through the immediate area, blackening and setting fire to the rest.
They raced through the door, Aohdei boosting the flames with his own, effectively destroying the gate.
Aohdei called back to Rylzyr, "It's only a matter of time before-" the gate came crashing down around them, splitting from itself, timbers coming loose and falling to the ground, splintering and shattering like char, "Yeah, that. It should hold them for a while." As the horse galloped through the streets, Aohdei asked, "How long can you keep this up before the horse dies? I intend to leave this city alive, and headed south, not north and under guard."
