You return to the coffee house, tired after your exertions to find a very excited Rexus greeting you.
"I've done it. I've finished the translation. The last section speaks of how the leaders of the Silver Ravens had seen the writing on the wall- they knew House Thrune was likely to seize control and had come to the difficult decision to surrender should this event come to pass, hoping to prevent Thrune from razing Kintargo. Indications exist that the cache of treasures and documents hidden in the Fair Fortune were intended to serve as a sort of time capsule, should Kintargo forget the Silver Ravens with the passage of time.
There's something more. Reading through the documents I am convinced that my mother survived the Night of Ashes. The Sacred Order of Archivists have long used chambers below a local museum of oddities called Hocum's Fantasmagorium as a secret base of operations. If my mother survived the fire, she may have been silent for so long simply because she's been lying low in the chambers below the museum. The mithral key she left me supposedly opens many locks within the building."
Oh you can have more secret organisation rolls at this point too to see if the Silver Ravens grow.
