A ferocious bird with a wingspan of 100 meters hovers in the sky, casting large shadows. In the ruins of a deserted city, huge deformed humanoid monsters roam aimlessly. Dense colonies of man-eating ants march in the wilderness, killing all creatures they can meet. Gnawing on the sky and the dark sewer extending in all directions, the predator hiding in the darkness spreads its slender and ferocious limbs, waiting patiently for the fleeing people to break into their territory. Under the distant clouds, there is lightning and thunder, and one end is bigger than the mountains. The majestic giant bear, bathed in thunder and lightning, comes along with the storm. Let's welcome the storm! This is an era of catastrophe, a tragic beginning, and a carnival for the lucky ones!
