The Paradox Refinery is a Paradox base in Forbidden Valley and is carrying on the work of the Paradox Research Facility in Avant Gardens. Several Dark Ronin and Maelstrom Horsemen roam the path connecting it to the entrance to the Dragon Instance. This area also contains a small elevator down to a lone Horseman where players may rebuild three pipes for a mission. This is also the area where the Forbidden Valley Imagination Brick can be found.
