Cathedral of Abadar (Vyre)

From PathfinderWiki

The Cathedral of Abadar in Vyre lies along the infamous Heretic's Row. Like all of the other once-religious buildings, it has long been abandoned by its original congregation: worshippers of Abadar.

Most such derelict temples on Heretic's Row play host to a constantly rotating roster of vice and debauchery, but the Cathedral of Abadar does not. It has long been home to the Scarlet Sign, a malicious cult dedicated to maintaining a powerful political presence in the City of Masks. They are secretly led by a vrolikai demon called Vissagho.[1]
