Lyfrassir Edda is one of the few characters in the mechanisms canon to actually form an opinion on the Mechanisms themselves. Sure Ashes interacted with a bunch of characters as Hades, but those characters didn't form an opinion on Ashes. They formed an opinion on Hades. Hades was integrated into how their world and society operates. Its the same with Brian during High Noon Over Camelot. Brian is just part of their world, in a way that the prison mechs are not during the Bifrost Incident.
Lyfrassir is very aware that the prison mechs are exceptionally weird and annoying, and basically states that to the audience. They get to see them as the weird, slightly voyeuristic freaks they are. Like this is the only album where the mechanisms do not actually get involved with the full plot. In OUATIS Jonny, Nastya, and Aurora are the reason the defense grid in New Constantinople goes down and the final battle can happen. In UDAD Ashes got both Heracles, and Orpheus on the job for Daedalus, helping cause the entire plot for the album. Then HNOC has Brian trying to stop the plot and failing miserably. In TBI Marius, Raphaella, and Ivy are in involved just to fix the Black Box which allows Lyfrassir to see the plot unfold (and then know to try to escape the oncoming apocalypse).
The prison mechs weren't around for the main plot events in TBI at all, they show up to Yggdrasil afterwards during all of the chaos post-Bifrost Incident. So Lyfrassir knows they're space pirates who know how to work tech that no one else does, but more importantly they find the trio incredibly annoying. Lyfrassir Edda got to interact with the mechanisms as they actually were, and made the opinion of "God, I hate them" and I love that for them.
