Onward to the Disc Walkthrough
At the station, you can take care of any odds and ends that you need to before speaking with Ardyn. Once you depart you won't be able to divert for the rest of the chapter so be sure to take advantage of the opportunity.
You'll be following Ardyn's car yet again as you proceed to the Disc. Make sure to not lose him. Eventually, you'll reach a blockade and Ardyn will open the doors for you and part ways with you here. You are now free to proceed to the meteor site.
