Dacana

Dacana is the region Pokémon Iron and Topaz take place in. The region is based on Canada, which is why characters speak using the Canadian/British spelling for words. The region has Lush Forests, Snowy Mountains, Large, Deep Oceans, Deep Caves, and more. Compared to other regions, Dacana is the least populated region in the entire Pokémon world.
