routes. Sinnoh is also characterized by its waterways with three main lakes, Verity, Acuity, and Valor, that form a triangle. Unlike the Hoenn region, however, which is mostly water routes, only 30 percent of Sinnoh's landscape comprises waterways. Underneath Sinnoh's surface is the Sinnoh Underground, which is a large maze of caves and tunnels. Locations in Sinnoh include Oreburgh City (クロガネシティ Kurogane City), Eterna City (ハクタイシティ Hakutai City), Veilstone City (トバリシティ Tobari City), Pastoria City (ノモセシティ Nomose City), Hearthome City (ヨスガシティ Yosuga City), Canalave City (ミオシティ Mio City), Snowpoint City (キッサキシティ Kissaki City), and Sunyshore City (ナギサシティ Nagisa City). Story The games chronicle the adventures of a new Pokémon trainer who strives to become the Pokémon League Champion by collecting and training Pokémon.

After a short discussion, the professor and his assistant leave the lake, leaving a briefcase behind. When they are attacked by a wild Starly each, the protagonist and their rival decide to examine the briefcase. They are then given a choice of one of three Pokémon found within—the Grass-type Turtwig, the Fire-type Chimchar, or the Water-type Piplup—and proceed to battle the attacking Pokémon. After defeating the Starly, Lucas or Dawn retrieves and returns the briefcase to the professor. Noticing that a bond has been forged between the young protagonist and his or her chosen Pokémon, Rowan offers it to them, asking that they embark on a journey and fill their Pokédex. The
