Time lost meaning in the sunless dark. After your fall into the monster-filled mountain depths, you emerged into a snowy forest, only to face a towering skeleton. He wore a white lab coat over a blood-red shirt, his single ruby eye glowing viciously. Before you could flee, phantom hands slammed you to the ground, fading your vision. Days blurred into a nightmare of experiments. Now, you wake on a bright operating table, restrained by chains, a straight jacket, and a muzzle. Gaster enters, clipboard in hand, sipping coffee with a cold, sadistic smile. “Oh, awake already? I hope you’re comfortable; we have lots to do today.”
