The Celestial Orrery#
The Moon as Driveshaft: In the TYCHOS model, the Moon acts as the mechanical driver of the entire solar system—a driveshaft that keeps all other bodies in synchronized motion. The rotating gear teeth show how its orbit powers the entire celestial mechanism.
Radagon is Mars: The Moon-Mars relationship in TYCHOS shows Mars orbiting at exactly half the Moon's angular velocity—a 2:1 resonance. In the Lands Between, Radagon (the red-haired warrior god) is Mars. The dashed line shows the mechanical linkage: the Moon literally drives Radagon's motion. Mars does not move independently; it is coupled to the lunar driveshaft.
One Moon, Two Faces: Rennala's Full Moon and Ranni's Dark Moon are the same celestial body—just different sides. While Radahn holds the stars, we see the bright side (Rennala's domain, the Academy, order). When Radahn falls, the Moon turns to show its dark side (Ranni's domain, enabling the Age of Stars). Mother and daughter share the same celestial inheritance.
The Binary System: Marika and Radagon orbit each other as a true syzygy—two gods sharing one vessel but retaining distinct wills. The Erdtree sits at their barycenter, the axis around which all else revolves.
Radahn's Gravity: While Radahn lives, his mastery of gravity magic holds the stars frozen in place. Toggle "Stars Released" to see what happens when he falls—the stars resume their motion, the Moon turns to its dark side, and Ranni's ending becomes possible.
The Binary System#
The TYCHOS model proposes that the Sun and Mars exist in a binary orbital relationship, with Earth positioned at the barycenter, the center of mass between the two celestial bodies. This isn't heliocentrism. It's not geocentrism. It's something stranger.
In the Lands Between, we see the same structure reflected:
- Radagon and Marika form a binary system, two gods in one body, each retaining their distinct will. One shatters. One repairs. Neither absorbs the other.
- The Erdtree sits at the center, the axis mundi around which all rotates.
- Radahn holds the stars in place through sheer gravitational will, the force that keeps celestial bodies in their orbits.
This is the hermetic principle made literal: as above, so below. The cosmic structure of the heavens is replicated in the political and metaphysical structure of the world below.
Radahn Holds the Stars#
Starscourge Radahn learned gravity magic specifically to keep riding his beloved horse Leonard, who couldn't bear his weight after he grew to giant size. But this power scaled beyond the personal, Radahn used his mastery of gravity to hold the stars themselves in place.
This isn't metaphor. The stars in Elden Ring are literal celestial bodies with their own wills and destinies. Ranni's ending, the Age of Stars, requires Radahn's fall to even become possible. While he held them, the stars couldn't move. The celestial order was frozen.
Radahn is gravity itself. The binding force. When you defeat him, the stars resume their motion. New paths open. Ranni can guide the world into a new age. Miquella, in the DLC, can attempt his own new order.
Two bindings must break for true change:
- The Elden Ring (Marika shatters it)
- Radahn's gravitational hold (the Tarnished defeats him)
One breaks the metaphysical law. The other breaks the celestial law. Both must fall for the stars to move again.
True and False Syzygy#
Syzygy in pataphysics means the conjunction of opposites, but crucially, a conjunction where both elements retain their identity. It's not fusion. It's not domination. It's two distinct wills in perpetual opposition within a unified form.
Miquella and Radahn are a FALSE syzygy. In the DLC, Miquella attempts to create a new divine pair with Radahn as his consort. But this isn't syzygy, it's regression disguised as conjunction. Miquella uses his charm to dominate Radahn's will, erasing Radahn's identity rather than preserving it. One absorbs the other. That's not conjunction, that's the Law of Regression wearing the mask of the Two becoming One.
The Celestial Hierarchy#
The astrology of the Lands Between follows a clear hierarchical structure:
- The Greater Will — The distant outer god, the cosmic force that sent the Elden Beast
- The Elden Beast — The living incarnation of the Elden Ring, the vassal of the Greater Will
- Marika/Radagon — The god-vessel, the binary system at the center
- The Demigods — The offspring, the planets orbiting the central sun
- The Stars — Other cosmic entities, held in place by Radahn's gravity
- The Tarnished — The variable, the agent of change, the one who can break the orbits
This structure mirrors both ancient cosmological models and the hermetic worldview that Miyazaki draws from. The macrocosm reflects the microcosm. The political structure of the Lands Between is a map of the heavens.
