Spoilered because of plot details from the Alien RPG, which people might want to play without plot details being revealed.
Spoiler
As noted earlier in the thread, the concept art has imagery very similar to the vision that a Fulfremmen imparts during the Heart of Darkness Alien RPG scenario.
The RPG is really good at canon welding, and using material from Alien franchise media, including unused concept material. I'm thinking out loud here, but is it possible that the Prometheus saga would have concluded with something akin to the Fulfremmen and the Proto-Hives from the RPG, and that Shaw's fate in Covenant implies she might have been in the process of "Perfection".
