Tampere's Materiæ Abyssu (Rev. Matron Thorn) unveils its most ambitious and otherworldly creation to date. Joined by the enigmatic female vocalist Ishtariæ, whose spectral presence elevates the work into demonic, mystic dominions, the recording radiates with nightward majesty and forbidden intimations of occult allegiance.

The title "Aëthÿrinn Na Viixhræ" is drawn from the Lexethræum of Áltharósian mysticism, the New Age religion founded by Rev. Matron Thorn in 2025. Each composition reflects the core principles of the five Ëmpyrean realms as outlined in the Áltharós Oraclæum. In alignment with this metaphysical system, all lyrics performed by Ishtariæ are written in the meditative Áltharósian language, invoking the transcendent emanations that define this spiritual architecture.

Neo-noir futurism permeates the album's sonic design, weaving new age ritualism, darkwave gloom, industrial weight, dark ambient voids, and world-music inflections into a cohesive, apocalyptic vision. An expression of the human condition at the brink of transformation.

Mixed and mastered by Richard Corvinus (Swords Of Dis), whose production sharpens the album's transcendental edge.
