Hydrophilous Brood takes place in Pamugara, a dimensional nest immersed in a lush world where organisms are rematerialized into new hybrid species after passing through a powerful portal, a highly unpredictable artifact known as the ‘Mossbane Lantern’. Each song has a thematic connection to various artifacts on the previous album (Mossbane Lantern), extrapolating the characteristics and aftereffects of those artifacts within this temperamental environment of a planet.

Musically, Sallow Moth goes hand in hand with the aforementioned lyrical themes of transformation in that the continuous evolution of the project has become a signature feature with each album. This album retains a portion of the genre-shifting approach of previous works, but deliberately exhibits more focus on the intersection of technical death metal and brutal death metal, especially with the addition of a highly skilled drummer in Allen Gingerich. Notable influences on Hydrophilous Brood include Mortal Decay, Wormed, Deeds of Flesh, Cephalic Carnage, and Cynic.
