Padded paws softly thudded rhythmically across a forest on the outskirts of Cirrane. Four footfalls, silence. Four footfalls, silence. The smell of damp earth and the sound of crispy leaves tingled the large beast's senses.
She scanned the scenery through ice blue irises, seeing the world in varying shades of grey, illuminated by the luminescent glow of the full moon. The cold bite of the autumn air whipped against her dense, matted, black fur. It didn't bother her in the slightest.
She was far too large for any normal wolf, as tall at the shoulder as a smaller human even while standing on all fours. Despite her massive size, she maneuvered gracefully through the dense underbrush at incredible speed. Tree trunks and bushes in grayish high definition flickered in and out of view as her vision combined with her incredibly honed sense of smell to dart through nature's obstacle course effortlessly.
The hot, heavy breath escaping her predatory maw turned to steam in the chill night air. Her sharp fangs were prominently on display, pearly white and glistening in the moonlight. She was cloaked in a shroud of darkness by her midnight fur, traveling far too fast to be detected. The only chance an observer would catch sight of her would be by the glow of her eyes or the glint of her fangs.
She skidded to a stop and crouched her colossal frame to the forest floor, trying to pick up her prey's scent. A few rapid intakes of breath and...
There it was, clear as day itself.
Breaking into another sprint, she reached the edge of the trees and the cabin where her target slept.
A warm, yellow glow peered out of the single window. She could smell the burning wick and the melting tallow of the candle. She prowled up to the wooden door, silently and stealthily.
Standing tall and proud, the massive wolf began to shudder violently as it grew even larger. Her forelegs and hindlegs squealed as they expanded to even greater lengths, covered in dense muscle. The digits of her enormous paws elongated and thinned.
Her imposing snout began to recede even as her entire body swelled with large, dense muscle. The beast's maw shrank, sinking into her new, flatter face.
Then, with another violent, almost sickening shudder, the enormous wolf's thick torso shed all of its black fur.
Her now bare skin was elegant, creamy, porcelain, and smooth. Still hunched over on all fours, her forelegs began to transform into human arms and hands. Her dirt flecked claws turned into long, razor sharp fingernails. The fur in her footpads disappeared as her paws smoothed and flattened, leaving only a particularly large feminine pair of hands.
Her hindlegs transformed in tandem much the same way, turning into smooth, hairless, large human feet, proportional to her massive size.
She grunted, the mid-transformation moan sounding raspy, threatening, and positively inhuman. Her biceps and triceps bulged with powerful, swelling muscle, thick as tree trunks. Her forearms were dense and solid, strong enough to ragdoll a human about if she wanted. Her skin was smooth as silk, but tough as steel.
The mystical werebeast's bony hindlegs creaked as those bones grew even larger to support her massive frame and weight. Her angular joints straightened and lengthened, pushing her paws/feet out along the forest floor, carving deep grooves into the soft earth as they expanded.
