The note read:

"Don't forget your train passes that Selina got you for access to the Crown Tundra, just like with Natsu on the Isle of Armour, Fuyu awaits you alongside Glaceon the last of 3 Pokemorphs in Galar. Haruka and Sceptile will meet you at the Pouchers base and then you must defeat mother to fully clear out the pouchers in Galar. Use this map included so you can get your bearings"
