|Lake Sinoa Cave|
|Game||Tales of Symphonia: Dawn of the New World|
The cave only becomes accessible when Lake Sinoa, which the city of Luin is built upon, empties, and it is connected to the Tower of Mana. During the story, it is where Lumen's core is found. As the Summon Spirits of Light, Luna and Aska, make their pact at the Tower of Mana, the cave becomes a fitting resting place for the Centurion of Light. By the time Emil Castagnier awakens Lumen's core and the others are preparing to pursue Richter Abend into the Ginnungagap, Lake Sinoa has flooded with water again, making the cave inaccessible after halfway through Chapter 8.
