Rock album includes 'Illuminatus!' song [UPDATE]

I did not hear about it at the time, but in 2019 the Philadelphia rock band Eye Flys released the EP Context. And as Bobby Campbell mentioned in his latest newsletter, the album includes the track "The Triumph of Hagbard Celine." As with most Bandcamp tracks, you can check out the song before deciding whether to buy it. I had trouble making out some of the lyrics, but I did hear "submarine" and "immantize the eschaton" and other words.

"This is an album of commanding, lean noise rock absolutely brimming with vitriol," says the band, describing its music. More information here.  

Update: Please help Bobby with the lyrics; see the comments.
