Tarqaron

The Tower of Tarqaron was an ancient city that was located underneath Aspio until Duke ressurected it. It is the last dungeon of the game (excluding the Ex dungeon). When Tarqaron arises, it crushes/destroys Aspio. Through her connection with the spirits, Estelle learns that Tarqaron is a weapon powered by Mana which it would taken from Terca Lumieris]'s human popualtion, thus destorying the [[Adephagos and ensuring it would never happen again. The party make thier way to Tarqaron to stop Duke and preform the Spirit conversion to destroy the Adephagos.

Tarqaron's interior
Tarqaron itself mostly resembles the city it once was. The few exeptions are the large blue room that occupies most of Tarqaron's interior. The room is full of technology of the Geraios Civilization and extremely large apatheia that power Tarqaron. In a hidden part of this room you can find Uroborg and Susanoh, Rita and Repede's Fell Arms. The other rooms inside the tower are a cave-like maze, which is immediatly before the fight with Duke, and a circular room were Zagi is fought a last time before he eventually dies.

The top
At the top of Tarqaron is a garden were a person (in this case, Duke) can control Tarqaron. It is here the party confronts Duke. When the party explain the method of Spirit conversion Duke replies that they would save the world for the selfish desires of humans. He then goes on to tell the party of Tarqaron's true purpose. The Gerios bulit Tarqaron to destroy the Entelexia, Who attacked the blastia to stop the Adephagos from happening. When it did happen only then did the Gerios listen to the Entelexia. The party ask him if this is what Elucifer would of wanted, which provokes Duke to fight the party.

If all the seven Fell Arms have been collected an event will happen when Duke is defeated. The seven Fell Arms power up, but so does Duke. He will transform into another form called Radiant Winged One. In addition to being more powerful he will aslo gain another Mystic Arte, Brave Vesperia a mix of the party's Mystic Artes.
