Pokémon Brilliant Diamond/Shining Pearl: Valley Windworks Walkthrough

Valley Windworks, located east of Floaroma Town, is a massive wind-powered power plant. It uses enormous windmills to capture wind energy and convert it to electricity. In the story, Team Galactic led by Commander Mars is trying to take over the station to harness its energy, kidnapping a power plant worker and forcibly removing his daughter out. Until you kick Team Galactic out of the place, you will be stuck in Floaroma Town and cannot progress through. Here’s how you can get through Valley Windworks and continue your Pokemon journey past Route 205 in Brilliant Diamond and Shining Pearl.
