Location from Pokémon Platinum by Game Freak / Nintendo
The central lake south of Veilstone City — where Azelf lives, where Saturn's team Galactic operation drains the lake using a bomb to capture the Being of Willpower.
Lake Valor is attacked most directly. While Jupiter uses stealth at Lake Acuity and Mars captures Mesprit at Verity, Saturn's operation uses a Galactic Bomb to drain Lake Valor entirely. The player arrives to find Pokémon dying in the mud and an exposed lake bed. Azelf, the Being of Willpower, is captured in Valor Cavern. Willpower. The thing that allows humans to act despite difficulty. Saturn's operation against it is both the most violent of the three lake operations and the most philosophically coherent expression of what Cyrus is trying to eliminate. After the main story resolves, the lake refills. The Pokémon return. Azelf returns to Valor Cavern. The lake looks the same as it did before. The game doesn't dwell on what happened here.
A mid-sized lake that becomes a muddy basin after Team Galactic drains it — Magikarp and Goldeen flopping in the mud where water used to be. The transformation from lake to drained crater is one of the game's more visceral environmental violations. Valor Cavern sits exposed at the empty center.
