I'm working on a series of adventures set in Kaer Maga, and I am trying to find any canonic dates for when the Council of Truth was active. The group is mentioned in the Campaign Setting City of Strangers, the module Seven Swords of Sin (where they were introduced into Golarion), and in Pathfinder #63: The Asylum Stone.
We know that they were active in Kaer Maga starting in the fairly recent past, and then disappeared without a trace "some years ago."
Have the dates of when the Council of Truth was active in the City of Strangers ever been published? Were they active for a long time? (5 years? 50 years? 500 years?)
If there's nothing canonical, I'll just make something up, but I'd like to stick with canon if I can.
Thanks!
