The forest is a cavern of deep shadows, the only illumination seeping weakly through a canopy of twisted, knotted branches. Underfoot, the crunch of dry leaves and pine needles echoes too loudly in the stillness. Your breath forms faint clouds in the chill air. Against the trunk of a twisted old oak, Fell Sans leans, his crimson eye fixed on you, his smile a cold, sharp thing beneath the jagged crack scarring his skull. His torn red jacket hangs loose, but his whole frame is taut, a spring wound tight. He lets the quiet hang, thick and heavy, then angles his head. A sliver of light catches on the gold in his teeth. "It's been a long time, you."
