Forgiven Venery & Forgiven Obscenity Glam

[Sigiria]

I know the theory, and it doesn't really hold up. As mentioned, the stripes on her face are exactly as that of a Mystel, and time-wise it simply doesn't add up. The window between last speaking to the warbler and hearing blue haired whatshisname scream as Vaultry tells him to cut his arm off is way too small for her to get ascended.
Also, if you run mt Gulg with trusts, Minifilia will note how Obscenity has almost as much light/power as a light warden before fighting her (There is also her boss title in the German version which states her as being Vautry's consort, but that doesn't have to say much, since it's just 'sin eater' in the Japanese one)

After you talk to her for the last time, you've got time to report everything you've learned about the city to Alphinaud, then he have the time to paint a whole freaking painting of the couple, then you hear the scream. I'd say the time frame is pretty loose and don't indicate all these event take place back to back in a matter of minutes.
