A team of scientists embarked on an expedition to the Arctic Circle, aiming to study the effects of climate change on ancient glaciers. Dr. Helena Morse, a glaciologist, discovered a fissure leading to a vast cavern beneath the ice. Eager to explore, the team descended into the frozen abyss, uncovering prehistoric remains and cave paintings depicting unknown rituals. As they ventured further, they realized they were not alone. Something ancient and malevolent stirred in the shadows, awakened by their intrusion, and the team found themselves trapped in a frozen nightmare with no escape.
