To unlock the "Greener Pastures" trophy in Yonder: The Cloud Catcher Chronicles, all you need to do is reach the first biome. At the beginning of the game you can talk to everyone on the boat if you want or just head straight up to the captain and choose to forge ahead to Gemea. Wander around the boat a little longer as the wind picks up and eventually you will be shipwrecked. Speak to Aerie and you'll wake up in a cave. Head up the path until you spot a glowing light in the ground. Interact with it using
to get your first Sprite. Then interact with the purple haze (Murk) to have the Sprite clear it. Walk all the way up to the exit and you'll be treated to a lovely view of the fields as well as this trophy.
