I compiled this file as a quick reference to all the conspirators, tokens, and Harrow cards.
The second page of the file is a player handout, using what Biyo can tell the PCs about the realms and conspirators.
(In order not to give everything away to the PCs, I decided that Biyo doesn't know that Radiant Sunrise has become Mourning Choir, that the Barrow King holds her token, or that the Sonnerae-hag lives in the Prophet's Garden and also has a token. If you decide differently for your game, just change the handout.)
