In the frigid realms where ice and snow reign supreme, a colossal entity known as the Frigid Fortress commands both awe and fear. This mythical umbra, a living embodiment of icy dominion, possesses a vast central body that, in its dormant state, deceives onlookers into believing it's an imposing mountain. Four colossal legs, akin to a turtle's retreatable limbs, further contribute to its mountainous facade when it slumbers. The Frigid Fortress's head extends gracefully on a retractable neck, adorned with a majestic singular horn and an ethereal "beard" of crystalline ice on its lower jaw. This creature, in a rare display of animation, roams the frozen landscapes at a glacial pace only once every three centuries. Its movements, sluggish yet deliberate, perplex those unaware of its existence, leading to the mistaken assumption that maps might be flawed or that mysterious mountains shift locations. Over the ages, records of the Frigid Fortress have become elusive, shrouded in mystery as those who possess knowledge of this behemoth often vanish before it stirs once more. Misconceptions persist among the short-lived inhabitants of nearby settlements, giving rise to the erroneous belief that the mountain itself is the creature's dwelling. Unbeknownst to them, the true abode is the massive living entity, concealed within the illusion of an immovable mountain. To the nearby denizens, the Frigid Fortress is more than a mere giant; it is a living legend, a silent behemoth that weaves its way through time, leaving behind towns built unknowingly on its colossal form. The creature's glacial movements, obscured by the swirling snowstorms it conjures, go unnoticed by those nestled within its icy embrace.
