DLC released in 2 parts. First one is called the Book of Amber and will be a simple story: Machine is destroyed but Paradox forms (3 beasts in Scarlet, Swords of Justice in Violet) still appear.

You trace it back to the “Moondial” which is basically a giant terra crystal and fight the 3rd legendary in a Raid style battle.

Gyrados Regional Fake.

Part II: The “Moondial” can be used every hour for a random legendary raid similar to Hoopa Rings in OrAs, Hyperspace in UsUm, to get old legendaries.

Mega Stones return but no new Megas. Terra Stones can be equipped on Pokémon like Jigglypuff, Tyranitar, etc
