Forever Fog

Live in the forever darkness, with an impenetrable fog obscuring your vision at every step. The sun no longer rises, and the surface has been claimed by unseen horrors hunting in the gray. You must adapt to a world permanently locked at midnight, where survival means staying covered, constantly watching your back, and relying on sound over sight.

• When standing exposed under the open sky you gain Slowness 1.
• Mobs move faster, spawn faster and have increased player detection.
• All dimensions are always set to midnight.

Using shaders, resource packs, and additional mods for mobs will make the experience significantly more immersive and terrifying, so feel free to experiment.
