[X] [Goetrin] Disgrace. Graf von Saponatheim will be sending a representative to the town, and you expect they will be eager to be seen 'cleaning up' the town. Goetrin will likely be stripped of command and sent home in disgrace, tarnished with this failure in the eyes of his peers.
We do not have the evidence to prove he is a knowing heretic.
However. As several other people have said, when a witch hunter reports cult activity, you have an obligation to investigate that activity. No matter how much you distrust the witch hunter.
If he'd sneered at Markus, thrown him in jail, and then led a few squads to the ritual site, I would ignore all of his distrust and insults. The problem is not that he disregarded our nebulous legal authority. The problem is not that he treated Markus badly. The problem is that he did not do his job.
The most important part of a court-martial is not punishing the guilty party. The most important part is establishing a clear precedent. We want any future garrison commander to understand that there is a price to be paid for ignoring reports of cult activity.
[X] [Edel] Incompetent. You will make the necessary reports through the cult hierarchy to make it clear to the Arch Lectors the scale of Edel's failure. Likely he will be quietly 'promoted' to some forgotten corner of a distant abbey and a more appropriate high priest appointed. Perhaps Sigiwalt would like the job.
He's not a heretic. Honestly, I don't understand the people who want to make the accusation. Markus is not the kind of witch hunter who uses accusations of heresy as a weapon against his political enemies.
Edel is an incompetent. Before he cleared his buddies on the merchant council, he needed to be sure that those buddies were not up to some serious heresy. This isn't about being a good person; even if Edel is seriously corrupt, he has to know what's going on. He didn't.
[X] [Teugen] Repaid. You will have a quiet word with the councilman, and make him see the wisdom of burying the hatchet. His wealth, and his connections among the nobility of Reikland and beyond, will be of great help to you and your agents in the future.
Teugen seems like a pretty bad human being. However, he is not charged with protecting the people of his town from the Dark Gods. That responsibility lies with Edel and Goetrin.
The reality of our work is that we need allies in high places. As we've seen, the Empire works more on who you know than on what you know. We have to start building political connections so that we can do our job. If that seems like a bad system, it is. But you work with the world you have, not the world you would like.
[X] [Other] Arrange a fitting reward for Adhema and Ozzy.
[X] [Other] Give a glowing report on Sigiwalt and recommend that he be promoted.
[X] [Other] Arrange to pay for the murdered woman's funeral and rest in the nearest Garden of Morr.
[X] [Other] Arrest and investigate the Stevedores directly involved with guarding the ritual site.
[X] [Other] Enjoy the Schaffenfest with your companions while it still lasts.
[X] [Other] Return to the High Temple of Sigmar and spend some time praying for your god's guidance. You came face to face with a formidable servant of the Great Enemy and perhaps came out not unscathed. Clear you mind, find your focus, reflect. Fortify your soul to face the trails ahead. Maybe now, with you holy duty complete you will find a semblance of peace and answers.
