Wearily he trudged through the darkness, barely able to put one foot in front of the other. His limbs felt like lead weights threatening to drag him down into the blackness around him. His muscles ached and nerves blazed with the echoes of battles long since over. The darkness was absolute and he was relying solely on instinct to guide him. He had forgotten how long he had been travelling, it could have been hours or years. Exhausted he had almost given up when a soft light appeared. He felt peace. Renewed, Castiel hurried towards it, towards heaven, towards home.
