I have real mixed feelings about this one.

The good:
It's a sublime full cast production with wonderful direction and restrained sound effects, at least compared to the ludicrous and extremity of other audio dramas.
The script is great and something a big different for a Kyme Thiel story, which is refreshing.
A nice, little contained story that could for the most part be just a 40K story, aside from the Red-Marked and Thiel, and the whole Nightfane premise.

The not so good:
The story is a little messy and disjointed, from the how's and whys of the mission to the narrative and events around it.
Apothecary reading very obvious Chaos shit out loud after having been fighting the Word Bearers for years now.
Nightfane itself. It's not fully explained what's going on. With the infiltration and corruption of the Ultramarines wounded, but the story is bookended with pseudoscience that amounts to calling it 'fucked up PTSD'. As extremely neurodivergent person with C-PTSD, this hit close to home and highlighted that, while it's absolutely possible to go some amazing cosmic horror and pyschic/ mental/ physical corruption from Chaos, it's very easy to get into ableism and other icks. This certainly isn't the worst and isn’t outright offensive, but it does make the harmful and unhelpful mistake of using real medical conditions as a basis and direct comparison. Their needs to be a clear delineation between how existing medical conditions and experiences are treated with how the interest with/ and fictional magical maladies. This has long been an issue with eldritch horror and certainly isn't unique to Warhammer.

I really had a good time with this one and I really wanted to rate this higher, but the PTSD thing really took me out of it and made me view the messy storytelling a bit more honestly. The performanced and production are absolutely banging though.

I will also say that I listened to this as part of the Treachery and Betrayal collection, which I had taken a big pauss in my listen through because I think they really made a mistake of having all the Kyme/ Thiel stories back to back, especially as their quality and my own personal enjoyment of them vacillates wildly (I honestly cannot explain why the extremely short one of Thiel and Guilliman just chatting about strategy that is setting up the writing it the Codex Astartes is my favourite, it's just written and performed so well and is such a tight story and production), but this was a decent way to wrap this mini series up at least.
