It is a known habitat of the unusual ¦Ä Delta Species Pok¨¦mon, also introduced in the TCG.

It has three major islands, two which are connected by a bridge. There are also several smaller islands, two of which seem to be volcanic.

It slightly resembles the northern most tip of the Tohoku region of Japan, and the south western tip of the Hokkaido Island. If this is true, it could possibly connect very closely with the Sinnoh region.

It is a relatively small island region that is quite mountainous. There are four areas in Fiore, each named after the season it constantly experiences — Ringtown, Fall City, Wintown, and Summerland. Fiore contains 213 Pokémon that can be captured in Pokémon Ranger, but it does not have any Pokémon trainers. All of the people who live with Pokémon keep them outside of Poké Balls, much like pets.

The structures (most of which appear to be made of pieces of older structures) found within Orre lend a post-apocalyptic feel to it as well. In this region, wild Pokémon are rare, and can only be caught in specific spots, and only during the events of Pokémon XD: The Gale of Darkness

The archipelago is different climatically from Kanto, which is temperate while the archipelago is tropical. One effect of the different climate is that Pokémon found in the Orange Islands have different patterns or colors than are found on the main land. In addition, several of the islands feature unique Pokémon found nowhere else: one island is home to a rare fruit that turns Pokémon pink if they eat it, and another island is home to an Onix whose body is made of crystal rather than rock.
