Roria is the region where events of Pokémon Brick Bronze commences. It is entirely fictional — it is not based on any real-world location or any existing regions in core series Pokémon games.
Geography
Roria is made up of 2 islands. The main island, which shapes like an inverted L, houses most of the towns and cities. A mountain range known as Mt. Cragonos stretches across northern Roria, apparently blocking any humid southwest monsoon or maritime airstream passing through and making northwestern Roria a vast desert. The east coastline of western and southern Roria is bordered off by inaccessible hills which seem to be a ridge extending southward from Mt. Cragonos. That coastline, along with the south shoreline of northeastern Roria, forms into a large bay.
A rugged savannah takes up more than half of southern Roria. Separated from the savannah by a river associated with Lagoona Lake, western Roria mostly consists of plains and forests. The climate is quite mild such that most of the region is not frequently affected by adverse weather. In fact, only Route 11 suffers from non-stop sandstorm, and only Lagoona Lake rains constantly. Route 15 and Frostveil City are always snowy, but the snow is not severe enough to affect battles.
On the other hand, the small island to the southeast is Crescent Island. A town on the north shore contains Roria's Final Gym and the Headquarters of Team Eclipse is also located there, while a large cavern occupies the southern part of this isle. How the island formed into a shape of a crescent moon is a mystery. More outlying islands are located beyond the Roria Town Map as well.
Locations
This section contains spoilers!
There are currently 18 known routes, 5 revealed towns and 7 explored cities in Roria. Places that are only mentioned in-game but cannot be accessed yet are in italics and have a grey background.
A secret area behind Lagoona Lake, where the first 3 members of the Legendary Pokémon group Swords of Justice throw down a sword and vanish. The final member shows itself when all 3 are gathered here again......
The home of Rival Tess. It is also where Kyogre is summoned and where Manaphy Eggs washed ashore during the 2016 and 2017 Manaphy Events. A Battle Pier is constructed here for trainers to test their battling skills.
The 3rd Gym City and the scenic spot for sunsets. Cypress approaches the player after a long absence, but he talks like he has absolutely no idea who Linda is...
A secret cave to the north of Rosecove with a huge waterfall arc. A certain Legendary Pokémon is rumoured to emerge from the great waterfall once the player brings a certain Key Item here.
A wide mountain range that stretches across northern Roria. The Western section is divided into the following 4 parts and bypassed by the Sky Train. Eastern section is divided into Routes 13-16, with Fluoruma and Frostveil Cities inclusive.
The complex interior of western Mt. Cragonos, going spiral upwards. No longer operational, this place remains as a training ground. Many Rock-type Pokémon live here as well.
A rocky ravine with a glowing body of water only accessible after the player obtains HM3 Surf. Players can encounter Lapras here every Monday of the week.

Where the player along with Rivals Jake and Tess land after taking the airship. There are 3 apartments and a Pokémon museum. The dumpster attracts Trubbish every Tuesday.

A rugged route leading to eastern Mt. Cragonos, where the player cannot proceed to without Crater Badge. A farm can be found here despite the landscape.
Only accessible after 3 of the Legendary Titans are captured, "The Titan" Regigigas wakes up and breaks open from its statue... but will it fight the player right there though?
A downhill road on the southeastern mountainside of Mt. Cragonos where people ski and manoeuvre with hoverboards. Contrast Badge is required to access this route.
The valley features crossroads that connect Route 16 with Port Decca, Tinbell Tower and the Roria Victory Road. Frequent meteor showers happen overnight, with a few large and mysterious meteorites crashing to the ground.
A tropical rainforest and natural preserve area, where a very diverse selection of Pokémon, including a few species with unique colouration, can be caught in a different manner comparing to Pokémon battles.
An offshore isle shaped like the crescent moon, situated to the southeast of Roria Main Island. Contains the following 6 parts. Despite having a town with the final Gym, it is generally avoided because of frequent pirate activities, as well as "the Evil Djinn" being sealed somewhere on the isle......
Settlements on northern Crescent Island and the only town in Roria to have a Gym. Many pirates hide here while the final Gym of Roria is disguised by a sunken ship. The HQ of Team Eclipse is also concealed here.
Many Alolan Pokémon live on these islands, while there are also Z-Crystals for players to pick up. There is a site of a shipwreck, which may possibly break the heart of a certain Rival...
Exploring deeper on Lost Islands, more Alolan Pokémon and Z-Crystals can be found in this jungle, but gates marked with Unown language have blocked a couple of chambers.
A seemingly active volcano on Obsidia Island. Legendary Pokémon Moltres waits for the player's approach on the topmost platform.
Roria League
The Pokémon League in Roria follows the setting for most of the core series games, where the player must clear all 8 Gyms before challenging. The Roria League is located to the west of Cosmeos Valley. Identities of the Elite Four and Champion, though, remain in mystery.
Gyms
Players must defeat the following Gyms to advance the plot and become qualified to challenge the Roria League. Each Gym Badge increases the maximum level where Pokémon traded in, known as "Outsider Pokémon", will obey the player by 10, and some of these Badges unlocks certain HM field functions as well.
Although Roria does not have its own regional specific Pokémon, it provides an extremely diverse selection of Pokémon species, ranging Pokémon from 7 other regions. There are almost 740 Pokémon species available in the region as of now. There are no regional Starter Pokémon which are for Roria only — all 27 Starter Pokémon families introduced in the core series games can be chosen here, but not encountered in the wild. There is also no "Roria Pokédex": the Pokédex the player receives is set to National mode.
