Go to the Fair Fortune Livery. The Silver Ravens were heroes of their day. There is more info in the livery. Rexus’s mother was a member of the Sacred Order of Archivists, which were connected to the silver ravens.

The Fair Fortune Livery seems to be haunted by some kind of Poltregeist.

The party found a trap door leading down from the work room to some basement/underground area.

Clearing out some remaining monsters, the group finds a Silver Raven safe house and cache. They each take away some of the valuables, notably 6 Raven Figurines of power, and a coded message to decipher.
