Introduction
Sionareth has two moons — Veyra and Keth. Both orbit the planet in a tight, shared trajectory that would be unstable, unsustainable, and probably catastrophic in any ordinary universe. But in Sionareth, magic is as natural as gravity, and the moons behave in ways that are fascinating to astronomers, obvious to mages, and for the people of Sewer “something you really shouldn’t stare at for too long.”
1) Astronomy
Veyra
the larger of the two moons
tidally locked to Sionareth
always shows the same face
light around it behaves strangely: it bends, slows, and sometimes “rings”
orbital period: 36 days
Keth
smaller and faster
orbital period: 27 days
extremely elliptical orbit
once every 108 days, it passes directly through Veyra
some claim there’s a hole, others insist it’s an extradimensional portal
the passage is precise, repeatable, and physically impossible
during the event, light, shadows, and echoes behave unpredictably
Shared Orbit
Veyra and Keth move as if connected by an invisible mechanism. Astronomers say it’s “an unstable system that should have collapsed ages ago.” Mages say it’s “a stable system that collapses only if you look at it wrong.” The Academy says “our calculations behave like wet paper.”
2) Magic and Anomalies
Keth’s Passage Through Veyra
When Keth passes through the equatorial singularity on Veyra, several well‑documented but poorly explained phenomena occur:
light bends in the opposite direction
shadows run away from their source
echoes lag by a fraction of a moment
some people claim to hear a voice that isn’t theirs
reality behaves like a proposal, not a law
The Passage affects:
rituals
divination
the stability of certain artifacts
the mood of beings sensitive to light or sound
3) Cultural Interpretations
Astronomers
“This is impossible.”
Mages
“This is possible.”
The Academy
“Please stop arguing.”
Flatbearers (Advocates of Intelligent Carrying)
They claim Veyra has a hole because “Great Sionareth needs ventilation.” No one takes them seriously, but everyone enjoys listening to them.
4) Myths and Legends
The Origin of Keth
According to one of the oldest legends, Keth was once a continent that, due to the buildup of minerals and steam beneath its surface, “launched itself” from Sionareth like the lid of a pressure cooker. Since then, it has orbited the planet — cold, silent, and without steam.
A full version of this tale is recorded separately: → Legend of the Continent of Keth
Conclusion
Veyra and Keth are not just satellites. They are two worlds that shape the rhythm of magic, culture, and superstition. Whether the singularity on Veyra is a hole, a gate, or simply a misunderstood shadow, one thing is certain: none of this works without magic — and you don’t look at it twice unless you’re brave.
Addendum: The Great Conjunction
“While Keth completes its orbit in 27 days, the Passage occurs only once every 108 days — the moment when both trajectories align in perfect synchrony. Astronomers call it the Great Conjunction. The Lumins of northern Tal’gorr call it The day even beer tastes like violets.”
