Base creature: Young White Dragon (CR 6). This formidable dragon, roughly the size of a small warhorse, perches with an air of chilling dominance atop a jagged ice spire. Its pristine white scales, etched with faint battle scars, are perpetually rimmed with a shimmering blue-white frost. A cruel intelligence gleams in its piercing eyes, and a visible wisp of freezing mist curls from its powerful jaws, hinting at its potent icy breath. It claims the harshest, most windswept peaks as its undisputed domain, an apex predator of the frigid wastes.
