Perívallo Hardcover – March 16, 2026

Perívallo is not a place in the ordinary sense.It is a living moon-ancient, self-maintaining, and indifferent to observers-whose surface, atmosphere, and memory form a single organism. Its caretakers, the Eídos, arise only where care is required, applying attunement to preserve balance and withdrawing when their work is complete.When a dormant spore of Perívallo is discovered beneath the Earth's ocean floor, the encounter that follows is unlike any imagined first contact. No ships descend. No voices speak. A single human mind is briefly aligned with a world that learned restraint before expansion.The result is quiet-and irreversible.This 92-page illustrated volume pairs speculative fiction with atmospheric graphite plates by writer and artist Neil Powell, whose detailed renderings give form to Perívallo's living geology, alien architecture, and vast biological continuity.Book of the Living Moon is not a story of invasion or salvation, but of encounter-between a civilization shaped by urgency and a moon that has never needed it.
