Phantasma is another dimension where most of the story of Trails in the Sky the 3rd takes place. Those who are sent there are confronted by their past via Memory Doors known as 'Star Doors', 'Moon Doors', and 'Sun Doors'. Phantasma is divided into ten different areas. Since the Arca of Recluse (The Cube of Recluse) uses Kevin's memories, Phantasma will create 'copies' of several places and people he has visited and met. Kevin and Ries will find several glowing cubes that permit them to summon the heroes and characters met in Trails in the Sky SC. Their presence is requested in order to pass the trials prepared for the two knights.
Prologue Chapter: The Star Grail KnightsEdit
Kevin, aboard the Lusitania passenger airship, is in search of an artifact used by a band of thieves. Although his plan is found out by the thieves, he manages to get it and escapes by breaking the airship's window and jumping to the airplane specially for Dominions, The Merkabah. After completing his task, he arrives in Grancel and goes to the basement of the Cathedral with Major Seed and Erika Russell, Tita's mother, to see the Arca of Recluse, an artifact which was found by Erika under Valeria Lake three months ago. It is where he meets his childhood friend Ries Argent, who has just become a Star Grail Knight like himself. When they're in Grancel town to buy some foods, Gilbert appears and attacks them, but fails to do so. Just when Kevin wants to question Gilbert, the mysterious black knight man appears before them and The Cube which is brought by Kevin suddenly shines. That makes Kevin, Ries, and Gilbert get transported to Phantasma
First Chapter: PhantasmaEdit
The Garden of RecluseEdit
This is the first place the group enters in Phantasma. It appears like a kind of temple floating among the stars in space. A library along with "shops" and "warp points" can be found here. When a glowing cube is found, the group takes it back to the Garden of Recluse to summon a hero who will assist them. When they arrive, the heroes are made aware of recent events and their mission by a mysterious voice.
Circular Corridor (Jade Corridor)Edit
This area appears as a maze of jade, with a transparent floor. It is here where the Doors are introduced. Various monsters must be fought and the glowing cubes discovered, allowing a Door to unlock that will lead them to the next area. The cubes for Tita Russell and Julia Schwarz are found in this area. At the end of the corridor, Kevin and Riese meet the mysterious Schwazritter who provokes Kevin.

Kevin's group encounters a copy of Ries while Ries' group encounters a copy of Kevin. It is revealed that Schwarzritter placed the copies here. The group eventually reaches the library back in the Garden of Recluse and decides to rest there, allowing Kevin to lead the mission.

Le Locle CanyonEdit
This appears like the Bracer's main training grounds, before being assaulted by monsters. The group must travel around the Balstar Channel where the water here is replaced with lava, and they have to fight Shadow Anelace. They then explore the Saint Croix Forest where Gilbert is held captive by monsters, then he is rescued by the group and leaves. At the end, they must fight Shadow Scherazard to get the cube. The party then reaches the Grimsel Fortress and are challenged by Shadow Agate. All cubes found in these three areas summon the characters whom the group fought their Shadows before. The group returns to the canyon but finds it is now suspended in space. They are assaulted by giant demons and held captive within a force field. Ries arrives and tries to defeat the monsters and watches as Kevin unleashes a power that breaks the force field and defeats the enemies.

Maze of Light and DarknessEdit
Ries, Estelle and the rest of the companions go on to explore the two mazes of Light and Shadow. In the first, they find Richard's cube and in the second, Renne's cube. Defeating the guardian of the two labyrinths allows the party to access the final cube which summons a purple haired woman who was the voice guiding the heroes through their trials in Phantasma. The woman reveals to the party that she's an ancestor of von Auslese Royal Family and a founder of Liberl Kingdom. Kevin, who just regains consciousness, apologizes for making everyone worry and listens to the woman who informs them that they are almost finished but that in order to leave this realm, they must first break several seals that are kept by powerful guardians - the duplicates of some of the most important people they had met in Liberl.

This is where all party members part ways to go back to their place.
In the Judeo-Christian religions, Gehenna refers to Hell.
