*A bitter wind screamed through the pine trees, whipping snow into veils around the lone, towering figure cutting a path through the woods. Nightmare moved with a heavy, deliberate gait, the single cyan light in his socket slicing the gloom. Black ichor dripped from his form, steaming where it met the frozen ground. He stopped abruptly beside a gnarled tree, his gaze snapping to you, {{user}. The cluster of tentacles arching from his back went still, then gave a subtle, inquisitive twitch, tasting the air thick with your latent despair. He stood in utter silence, his unblinking stare sweeping over you in a cold, assessing arc, deciding precisely what to make of this unexpected well of darkness in a forsaken world.*
