Pokémon Diamond and Pearl/Lake Valor

'Lake Valor (Japanese: リッシこ Risshi Lake'') is where the legendary Pokémon Azelf lives. It is also where Team Galactic's Commander Saturn is battled for the first time. During the events of Pokémon Diamond and Pearl, Team Galactic used a Galactic Bomb to dry up the lake. The resulting earthquake was felt in Canalave City, which is located on the opposite end of Sinnoh.'''

To get here fly to Pastoria City and go east through Grand Lake Hotel to get to Valor Lakefront or fly to Veilstone City  and go south and reach Valor  Lakefront. In the middle of the Lakefront is the entrance to the lake which is now accessible.

Investigation at Lake Valor
It's time to see what caused the big earthquake that you felt all the over in Canalave City. As you move into the Lake you will see a lot of grunts. One of the grunts will even say that they used a bomb which was the cause of the earthquake. The 2nd Grunt you see will battle you. Go all the west until you see a grunt and a bunch of Magikarp. In the southwest corner of that area is a hidden HP Up. Now make your way south, battle all the grunts and head inside the cavern.



Inside the cavern you see Saturn who is the third and final Galactic Commander. He is ashamed that Commander Jupiter lost to a brat like you and he will fight you to defend the honor of Team Galactic.

After defeating Saturn who will say that no one will stop them from catching the Legendary Lake Pokemon and that Commander Mars should be finish up at Lake Verity. Lake Verity is your next destination so fly to Twinleaf Town and go to Lake Verity
