| Colony 9

Colony 9 is the starting point of the game. It is one of two such colonies that have not yet fallen to the Mechon. Colony 9 is where Shulk, Reyn, Dunban, and Fiora all live and grew up. It is located on the foot of the Bionis.

The Colony is surrounded by water. The land that it does have is covered in lush grass. You'll find a variety of enemies in this area including bunny-like creatures called Bunnits, crab-like creatures called Krabbles, and many others as well.

| Bionis' Leg

The Bionis' Leg is located on the leg of the Bionis, between Tephra Cave and Colony 6. Gaur Plains is the wide field the party will first see when they enter the Bionis' Leg.

This massive area is consisted of two levels. It is almost comletely covered in grass. There is a huge lake on the eastern side of the lower level, which is fed by a waterfall above it on the upper level.

| Makna Forest

Makna Forest is the warm, temperate forest that the Nopon make their home in. It lies on the Bionis' back. It is entered via the Bionis' Interior, and contains exits to Frontier Village and Valak Mountain.

It is split in two by a great chasm, through which a fast-flowing river flows at the bottom. The river is fed by the beautiful Makna Falls, found near the forest’s entrance. It’s a huge area to explore, and there are plenty of difficult places to find.

| Eryth Sea

The Eryth Sea is accessible through a warp from Frontier Village. It is from here that the player can access the High Entian city of Alcamoth, the High Entia Tomb, and Prison Island. There are multiple Hovering Reefs which are connected via High Entian teleportation technology.

Sometimes at night, the weather will change to the rare shooting star effect, which is quite the spectacle if you're lucky enough to view it.

| Sword Valley

The sword of the Mechonis, which pierces the side of the Bionis. Sword Valley can be entered on foot via Valak Mountain and leads to Galahad Fortress. It was here, in Sword Valley, that the Homs made their stand against the Mechon in the Battle of Sword Valley.

Blood from the Bionis is drawn through the sword into Galahad Fortress, located at the hilt of the sword. Large gates partition portions of the valley, but several small side passages allow the cautious to bypass the gates.

| Gormott Province

Gormott Province is a Nation in Xenoblade Chronicles 2. The region was once an independent nation from the Gormott Titan, but it fell under Ardainian control. This territory is home to the Gormotti people, whose main settlement is the town of Torigoth.

Nature is abundant on Gormott, covered in lush plains and forests, and the accessible areas are affected by the movements of the Cloud Sea.

| Kingdom of Uraya

Uraya is a whale-like Titan. It is ruled by the Kingdom of Uraya from Fonsa Myma being their main city, whose territory is contained within the vast cave spreading through the Titan's body.

The caves are lit during the day by a faint sunlight filtering through the translucent membranes on its back, and at night by bioluminescent plants.

| Empire of Mor Ardain

It is a militaristic empire from the Titan Mor Ardain. They are led by the Emperor Niall. They control Titans through mechanical means, and bring heavy armaments as they annex other lands in a bid to save their own from ruin and depletion.

The Empire occupies other regions of Alrest with bases such as Torigoth Relay Base in Gormott Province and the Ardainian Garrison in Temperantia. The capital of the Empire is Alba Cavanich.

| Kingdom of Tantal

It is a force that rules from within the Titan Genbu. Little is known about Tantal and Genbu since the kingdom is an isolationist state, strictly controlling entry.

Like Uraya, the Titan swims beneath the Cloud Sea and everything lives inside it. Its climate is far colder than other Titans and is the only Titan seen with snowfall.

| Leftherian Archipeligo

It is actually a vast series of island Titans and small villages connected by bridges and tunnels through the Cloud Sea. This area includes Fonsett Village, where Rex our main protagonist grew up.

The Leftherian Archipelago is not like the other nations in that it has no distinct central government. In fact, the only civilization in the Archipelago is Fonsett Village

| Aetia Region

The remains of the Gormott Province and the Bionis' Leg make up a majority of the Aetia Region. Colony 0, Colony 9, Colony Gamma, and Colony Omega are located in this region.

| Primordia

It is the continent where the White Whale's Habitat Unit, now New Los Angeles, crash-landed after the Ark Ship was downed by the alien faction pursuing it.

It is the first continent visited, being where Cross is awakened by Elma in the prologue. The region features open grassy plains, large bodies of water, and several tall rock formations.

| Oblivia

It lies to the east of Primordia. Oblivia is a dry, arid region with sparse vegetation.

More enigmatically, it contains numerous ruins, is interwoven with gigantic metal water pipes, and hosts several colossal ring-like structures left over from a forgotten alien race that once lived in ancient Mira.

| Noctilum

It lies to the northwest of Primordia. Noctilum is very reminiscent of a jungle, with lush greenery and murky swamps.

Much of the region is bordered by tall crags that separate it from the oceans of Mira, with some lagoons where gaps meet the ocean.

| Sylvalum

This region is characterized by its white sandy terrain and exotic spherical trees. It lies to the north of Primordia

A massive glowing sphere can be seen over the southeastern part of the region. This region connects to Cauldros in the north.

| Cauldros

Cauldros lies to the north of Sylvalum. The volcanic terrain is broken by pools of molten rock, ancient battlefields, and the ruins of an ancient city.

Due to the hostile terrain and at times hostile weather, it is the most difficult region to explore.
