Construct a dark, game-style background image where a cloaked wizard, hat atop his head and a staff in hand, stands beside a treasure chest graven with the Bitcoin symbol upon its lid, placed amidst the eerie depths of an ancient forest. Capture the essence of a 'Dark Souls' universe with a palette of ominous greys, earthy browns, and faint golds under a canopy of twisted trees. The ambient lighting barely reveals the wizard's stern features; his eyes fixed upon the chest as a subtle glow emerges from the Bitcoin emblem. Nearby, hidden within the clutch of shadows, a goblin's silhouette can be seen, eyes gleaming with greed and cunning.  --s 600
