This is our walkthrough for Mission 13 in Pokemon Legends: Arceus called Disaster Looming! Below you’ll find each objective for the mission and how to complete them so expect to find some spoilers.
Go outside and see what’s happening
Exit your quarters to trigger a cutscene. When it concludes, follow behind Cyllene toward the front gate. Again, another cutscene will trigger.
Seek out Lian
Travel to Grandtree Arena to trigger a cutscene with Lian.
Seek out Mai
With Lian unable to help, make your way to Mai at the Worn Bridge.
Speak to the person who dwells here at the retreat
Approach the house to trigger a cutscene.
Choose whose help you want on the path ahead: Adaman of the Diamond Clan or Irida of the Pearl Clan
Exit the house to trigger another cutscene during which you’ll have to side with Irida or Adaman. If you side with Irida, you’ll be able to catch Palkia in whatever ball you want and Dialga will be caught with a specific ball later during the story. If you side with Adaman, it will be the reverse. You’ll be able to catch Dialga in whatever ball you want and Palkia will be caught with a specific ball later during the story. To sum it up, no matter who you choose, you’ll still be able to catch both Palkia and Dialga! At the conclusion of the cutscene, the mission will complete and you’ll receive the next 3 missions all at once.
