Asombro

The Asombro region is a region of the Pokémon world and serves as the setting of Pokémon Journeys: The Orb Quest.

Location
It is known to be nearby Johto, as people in this region are taken to Johto relatively quickly via boat. It is also known to be nearby all the other regions (but not especially close), as it features Pokémon from all of those regions, but not any undiscovered Pokémon.

Etymology
According to the game's staff, the name "Asombro" means "astonishment" in Spanish, which references how many people in the region are timid and easily shocked.
