[X] Plan Sneaky Heretic
-[X] First and foremost, scry Ser Garth and see where he is as well as who he's meeting with.
--[X] Continue having him monitored so you can immediately rescue him if necessary.
-[X] Do some cursory work and check on the septon's sympathies, see if you can find out who he's in communication with.
--[X] After finding out what you can, go meet with Lord Hightower and bring up these suspicions. If necessary, deflect blame from Lynesse by pointing out you have been investigating Lucan quite heavily.
-[X] In the meantime, contact Yrael, and ask that he and a few Archons go to Whitehead Keep and publicly (and safely, no unnecessary risks) free Septon Dondar. That man is one whose preaching will lead to a land of more tolerance and peace, he must survive. His chances will be greater if he is seen to have divine blessings.
--[X] They don't need to talk if the questions asked are awkward. Their only goal is to be seen while freeing Septon Dondar.
--[X] Send Dany with them to serve as the mouthpiece if needed as well as to fight with them should any surprises pop up.
--[X] They are to be backed by Yss divinations to make sure that no nasty surprises are waiting for them.
