Ideas for a new expansion

[SaitoHikari]

About the Siren discussion: It's fairly clear that the Siren in Pharos is only one Siren, and they're not very common in Eorzea.

You actually run into a second Siren at the end of the Bard HW storyline, one that was sealed away by the Moogles of the now deserted Sea of Clouds colony. (It's stated/implied that she killed most of the Moogles there before being sealed in one of those mysterious egg-shaped rocks with runes on it, and then she tries to kill you and your fellow Bards after your group accidentally frees her hundreds of years later.)

She was pretty much identical to the first Siren in Pharos Sirius, so it's likely there's a whole beast tribe of them out there somewhere.
