I enjoyed the story overall, although there are some gaps that I still am left wondering about. In particular, it would be nice to know how Azem predicted our arrival on Elpis. I also wish that there were more details around what happened in the past after Abyssos, especially from Lahabrea and Elidibus' perspectives, especially after Elidibus was planning on speaking further with Azem about what they had foreseen, although there are probably opportunities to expand on this in short stories.
The P11 arena is fairly interesting, with 14 Convocation seats, and Lahabrea/Mateus' full glyph present on a couple of pillars (presumably due to his position as Speaker).

The biggest surprise was around auracite, and the optional reference to Ultima, the High Seraph. I'm glad that the concept is tied to something external to Amaurot, as it creates fresh opportunities for story potential and another potential threat external to Etheirys.
It will be really interesting to see what comes of P12S phase 2. While we've already seen Ultima represented in the story, I'll be curious to see if Athena's corruption through the Heart of Sabik gets linked back to the Lucavi with her final form.
