The precise mechanism behind the functioning of the Wings of Light is never explained in detail, though in its destructive capacity, the device seems to harness the power of Nerifes itself in order to destroy the land by imposing a large flower-shaped glyph over it, and would presumably have performed some similar feat when raising it. The interior of the Wings of Light contain many advanced technological machines, such as computers and elevators. The interior of the area are comprised of walkways connected by electrical wiring and teleporting devices. The final levels of the Wings of Light are comprised of geologically-active fields in which shipwrecks and the remains of ancient monsters are abounded. The very end is the control room, where the Merines is able to control the device.
After the departure of the Ferines from the Mirage Palace, from which the Wings of Light apparently must be raised through an act of Nerifes, the player party must infiltrate the facility through the tram discovered in the underground. The Trail Across the Heavens connecting the lighthouse of Werites Beacon to the Wings of Light is mentioned in an Oresoren legend, in which an ancient hero crossed it for the completion of his quest. While traveling to the top, the party meets ups with Walter Delques. Walter uses the Whisper Crystal to summon Royal Automata to fight the party, despite the party's plea, they are forced to fight the automata and they defeat it. After defeating the Royal Automata, Walter dies from exhaustion from powering the machine. The party looks at Walter’s corpse and wishes there was another way.
After arriving in the control room, Maurits Welnes attacks the party as a last resort to stop them, but he is defeated twice. Senel Coolidge and the others manage to return Shirley Fennes to her senses and decide to return to Werites Beacon, but they notice Maurits is gone. Maurits attacks the party and assumes the role of Merines for himself, leading to his possession by the Raging Nerifes. The Raging Nerifes grabs Shirley and holds the party to the ground. Senel receives the blessing of the Quiet Nerifes and is able to break free from the hold. Senel runs up to the Raging Nerifes and manages to free Shirley and the others. The Raging Nerifes attacks the party, but they emerge victorious. After battle, Senel falls from the last floor of the facility following the defeat of the Raging Nerifes, Shirley jumps after him and performs the Rite of Feriyen.
The party returns to the Wings of Light during Grune's character quest, after Nerifes tells the party that Grune is located there. When they arrive at the top floor of the facility, they find Grune and Schwartz fighting, Schwartz tries to depose of the party, but they block her attack with their Sacred Eres. Grune's memories reawaken and she is determine to kill Schwartz at any cost. Schwartz then attacks the party and they fight her briefly, but it turns out she was just toying with them. Schwartz leaves to the Cradle of Time and the party returns to Werites Beacon.
- The Wings of Light is one of three dungeons in Tales of Legendia not accessible from the World Map. Both Mirage Palace and the Wings of Light are connected by the surviving remnants of the ancient tram system. The other location is the Cradle of Time, which can be reached through a portal at the Altar of the Sea.
- Turning Prayers into Power is the location theme for the Wings of Light, which plays for the interior floors of the dungeon. Ancient Ship plays for the final floors of the dungeon. Both tracks can be found in the original soundtrack as Tracks 40 and 12 respectively, and are composed by Go Shiina.
- The Wings of Light is one of two dungeons that has two different background themes, the first being Turning Prayers into Power, and the second Ancient Ship, a trait it shares with the Bridge, which has both The Legendary Sorcerer and Guiding Star for its backgrounds. Both pair of songs share the same melody in different arrangements.
