Prompt: The Slumbering Sentinel Deep within the heart of the icy realm of Planet X, there lies a colossal being, a living mountain known as the Slumbering Sentinel. This immense Frostwyrm, spanning multiple kilometers in length and reaching a towering height of 12 kilometers, is a creature of both wonder and awe. Unlike its agile and active counterparts, the Slumbering Sentinel spends its existence in a deep, timeless slumber. On the colossal back of the Slumbering Sentinel lies a frozen landscape, a landscape that spans a considerable portion of the planet's surface. This icy expanse is home to the sacred Frozen Spire, the legendary peak where elder Frostwyrms ascend in their final days. The Slumbering Sentinel, in its majestic repose, unknowingly harbors the very sanctum where life and death weave their mystical dance.
