Phoenix eggs were formed when a Phoenix perished, leaving behind a blazing cinder that hardened into a gem-like shell, almost completely immune to harm. Weighing around five pounds, these eggs remained unbearably hot until they hatched into a new phoenix within days or weeks. Alchemists and Mages prized them for their rarity, as fragments of phoenix eggs were believed to hold immense magical potential, often serving as key ingredients in advanced potions, Elemental wards, and rituals of fire and renewal.
