The vestiges of a flooded city from a previous age form the foundation of these ruins. It is known as one of the safest exploration spots on Marble Blue, making it a popular destination for novice explorers.
A creature of note here is the mocktopus, one of the wardens of the great seas. Legend says that the nest of the mocktopus is somewhere in these ruins, filled with treasures that it has collected over the years.

Giant sunflowers bloom around a derelict battleship in this area, one of Marble Blue's most popular scenic spots.
But hundreds of years ago, this was a place of death, a war-torn wasteland that people dared not approach.
Some sections of the battleship's interior are still operational, and some say that it houses an ancient weapon of great power, waiting to be activated once more.

It is said that this tree which grows beyond the clouds became thus due to the various pollutants that were released into the environment by the previous civilization. Such dark history aside, the flowers that grow in this area are renowned for their revitalizing properties, and are popular gifts.
Furthermore, the World Tree is said to bear a single fruit every hundred years.
That hundredth year is precisely when the protagonists make their visit.

The airship owned by Shyamalan, the leader of Sheva.
At first glance, it looks like any other luxury liner, but a closer examination reveals dark corners such as an execution chamber, indicative of Shyamalan's cruel nature.
Visitors can teleport directly onto the ship from the spaceport, but as it is technically Shyamalan's "territory," all visitors must be accompanied by a Rank III explorer or higher.

A great sea of magma that sprawls across Marble Blue's northern hemisphere.
Teleport sites are limited due to the great amount of magnetic interference in the area.
This, and the high concentration of dangerous monsters in the area make deep exploration extremely difficult. It is said, however, that in the depths of the Magma Ocean lies Primordia, the center of the world, and the place where all life began.

The bright illuminations adorned across these silver peaks gives it a magical atmosphere, but deep within its range, constant blizzards blow.
Countless explorers have entered these mountains, and never returned.
However, in the vicinity of the golden tree at the summit, the popular freeze gift "Light of Polaris" can be found, leading many explorers to brave the risk.

As the name suggests, this maze area is constructed with confectionary material.
It is indeed a land of fantasy, brought into existence through a specialized gift, but many explorers who wander inside find themselves overwhelmed by the surreal environment, doubting whether what they are seeing is real.
A great castle towers in the middle of this labyrinth, but not one explorer has made it within its walls.

Previously uncharted ruins discovered by the protagonists on the seabed.
The ruins themselves are a gift, an ancient uninhabited castle, whose majestic visage can be seen shimmering between the moon and the sea.
The Explorer's Guild sent in an advance team upon its discovery, but they found that certain sections were made inaccessible by strange, rune-like patterns.
Thus, many of the castle's mysteries still remain hidden.

A quarantine area whose existence has "officially" been denied throughout history.
Only the countless generations of Thousand Voyagers are even allowed entry into the facility. The reason for its existence, it is rumored, is to isolate some "entity" from the rest of civilization, but nothing more concrete has ever been discovered. Currently, the facility is being overseen by a single Thousand Voyager.

When the protagonists are marooned on a deserted island, they discover these ruins in the catacombs below.
As it was built below sea level, many areas of the ruins are submerged.
As it was a facility built by the previous civilization, it is thought to contain clues about the origins of Theia.

A dreadnought-class battleship owned and operated by Volhelm Industries.
It is an iconic vessel within the Volhelm Industries arsenal.
As it is equipped with its own teleporters, it is able to carry freight between Marble Blue and Theia without the use of spaceports.

An area said to exist beyond the Magma Ocean.
It is an intensely treacherous area, with skies constantly bathed in magma, and powerful monsters lurking everywhere.
Even Rank IV explorers, on an expedition that lasted several months, were only able explore 70% of the entire area.

Beyond Primordia lies the ruins of a metropolis built by the previous civilization.
Like Primordia, it is now home to many dangerous creatures, and the meteors that shower down from the magma sky actually puts it a tier above Primordia in terms of danger level.
It is said that at the end of the light that extends form the central area, is the entrance to Paradise.

A vast space that extends underneath Satellite Base Theia.
Possibly due to the effects of miasma, the monsters that inhabit this area are much more savage and volatile than the monsters on Marble Blue.
