What do you do in Pokemon Pearl after you beat Candice?

Answer 1

In Pokémon Pearl, after beating Candice, head to Lake Acuity. You'll see your Rival and a Team Galactic Admin Jupiter battling. Jupiter leaves. Head to Veilstone City. Head over to the big black building in the back of the city, this is Team Galactic's Headquarters. Talk to the Team Galactic Grunt that's standing outside and he'll drop the Storage Key. Pick it up and head into the Warehouse area which is the area in which you picked up the Fly HM earlier in the game. Use the Storage Key to open up the door that is inside the Warehouse and you'll be allowed through. Go through the building and you'll eventually find the Galactic Key. Leave the Warehouse building and enter into the main doors of the Galactic Headquarters. Open the locked door on the first dor and proceed up the stairs. Continue through the building and you'll eventually do battle with Cyrus, the Boss of Team Galactic.
