Hello all,

I'm thinking about running Prisoner 13 in my upcoming Wildemount campaign.   And I'm stuck on something, which is how to hook the PCs into it.   

My campaign starts with the PCs being a bunch of humanoids in Urzin and running the Unwelcome Spirits adventure.  I am trying to run the campaign as a sandbox where possible.  So I would prefer that rather than an NPC organization or individual coming to the PCs and hiring them to go and break out or interrogate Prisoner 13, the PCs find out about her and her secrets and decide to go kick off the adventure themselves.  Less "Quest" and more "Player Agency".    Any suggestions on what rumours or info the PCs could stumble upon, and how they might learn this in or around Brokenveil Marsh?

Additionally, I'm thinking of using the Luxon Beacons as a theme in my campaign, so am hoping to have Prisoner 13 have some information or knowledge that might lead towards one of the Beacons.   So as an added bonus, any thoughts on that would be very helpful!

Thanks in advance
Blakey
