Siren's Tower is a location in Final Fantasy Brave Exvius. It is a tower built that was at one of Grandshelt Isles's smaller islands to the east (and is thus a part of the Kingdom of Grandshelt's established territory). It is home to the esper Siren.

The player must defeat her at the stage 'Siren's Tower - Top Floor' and she will join the party. The stage 'Bewitcher's Trial' appears when Siren (1★) reaches level 30, while 'New Trial of the Bewitcher' appears when Siren (2★) reaches level 40.


Spoiler warning: Plot and/or ending details follow. (Skip section)

Long ago, Siren was sealed away in the Tower due to its fearsome power. However, the eventual breaking of the Earth Crystal by Veritas of the Dark weakened the seal upon it and allowed Siren to break free once more.

Two knights of Grandshelt who witnessed the crystal's shattering, Rain and Lasswell, journey to Siren's tower in hopes of receiving help from the esper so they can become stronger. Upon completing her trial, they are bestowed with her power, and are also given a request that they restore light to the world.

Spoilers end here.




Sirens are from Greek mythology. In the story of Odysseus, the Sirens are beautiful women who lure sailors with their voices. Odysseus escaped the Sirens by having all his sailors plug their ears with beeswax. He was curious as to what the Sirens sounded like, so he let himself be tied to the mast to ensure he could not fall victim to their voices.
