A resounding boom erupted across the dying grassland. A loud wailing war-cry echoed over the field, the sound of heavy hooves trampling the ground as a large form dashed across the plains. The speeding form soon slowed to a mere run, than stopped suddenly, skidding and kicking up more dirt as the horse-like being stood still.
Standing near the edge of a cliff overlooking a small village below, a fearsome centaur warrior looked down below, hefting a powerful club over her shoulder. Two large horns curled above her head, with bright ginger hair spilling down her back. She pawed a hoof at the ground, kicking up more dirt and sending a stray stone down the cliff side.
"Well, if this isn't a cozy lil world. Could use a bit of shaking up I suppose," the warrior chuckled to herself, standing her great-club against a rugged stone. "Of course, it isn't a siege without an army." The warrior's eyes shined red, a wave of red and green mist beginning to pool beneath her hooves. A glow began to form behind her, before the sound of more hooves on dirt began to emanate. Ghostly centaur figures, wrapped in mists of red and green stepped in line with their leader.
"Eh, that'll do. Have to find some locals eventually. If they can keep up." The warrior laughed, before she turned away from the cliff, charging down the mountain, her army of ghostly centaurs following her.
