The Quartz and Topaz Giratina Event! Whenever the game comes out, an event will be available after completion of the game. The roaming PORTAL?! The Distortion world portal will roam cities and towns of Valina randomly and will change spots every so often. If you go to the town where it's located, you can enter the portal to the Distortion World. A pretty short puzzle and path will await you inside, and Giratina waits at the end. You can Battle it then!
