The Operational Calendar of Vôrun-Hold
The Operational Calendar of Vôrun-Hold
Based on the Orbit of Hypnoth and the Rings of Hpnoth Tertius
Within the Vidar system, time is not measured by arbitrary division but by predictable celestial cycles.
The Hold aligns its operational schedule to three dominant motions:
Hypnoth’s rotation — defines the working day.
Vôrun-Hold’s orbit around Hypnoth — defines the Shadow-Shift cycle.
Hypnoth’s orbit around the primary star — defines the operational year.
These cycles form the Vôrun Calendar used across the Hold’s civilian and industrial sectors.
1. The Hypnoth Day
Hypnoth rotates faster than Terra.
Parameter
Value
Length of day
10.0 hours
Daylight period
~5 hours
Night period
~5 hours
Total days per year
~617 days
However, Vôrun-Hold does not use the Hypnoth day directly.
The Hold operates on Orbital Time.
2. The Orbital Day (Vôrun Cycle)
Vôrun-Hold orbits Hypnoth every:
14.3 hours
This orbital period defines the primary work cycle of the Hold.
Parameter
Value
Orbital period
14.3 hours
Cycles per Hypnoth year
~431 cycles
Cycles per Terran day equivalent
~1.68
Each orbital cycle includes a period when the Hold passes through Hypnoth’s shadow.
This event is called:
Shadow-Shift
3. Shadow-Shift
When Vôrun-Hold passes behind Hypnoth relative to the star, the Hold enters planetary shadow.
Duration:
~55 minutes
During Shadow-Shift:
exterior illumination drops sharply
thermal radiation declines
visual sensors recalibrate
navigation protocols shift
For most Kin this is simply:
The dark phase of the work cycle.
It is not ceremonial.
It is predictable maintenance time.

Parameter
Value
Occurs every
14.3 hours
Duration
~55 minutes
Cycles per year
~431
Uses include:
• external hull inspections
• shield recalibration
• heat sink cycling
• long-baseline sensor sweeps
4. The Hypnoth Year
Hypnoth completes one orbit around its star every:
257.3 Terran days
Converted into Hold cycles:
Parameter
Value
Orbital year
257.3 days
Hold orbital cycles per year
~431
Hypnoth rotations per year
~617
The Hold divides the year into Operational Sectors rather than months.
5. Operational Sectors of the Year
The year is divided into 8 sectors for logistical planning.
Sector
Cycle Range
Operational Focus
I
1–54
Structural inspection season
II
55–108
Deep salvage operations
III
109–162
Refinery load balancing
IV
163–216
Crucible optimization
V
217–270
Orbital maintenance
VI
271–324
Long-range Hernkyn expeditions
VII
325–378
Belt harvest season
VIII
379–431
Annual recalibration and audit
These sectors exist for logistical clarity, not ritual.
6. The Ring Sky of Hypnoth
The destruction of the moon Hpnoth Tertius created a debris ring around Hypnoth.
From the planet’s surface this ring appears as:
a pale arc crossing the sky.
The ring plane is almost aligned with the planetary equator.
This creates seasonal visibility patterns.
Ring Visibility
Latitude
Appearance
Equatorial
bright arc overhead
Mid-latitude
diagonal band across sky
Polar
low horizon arc
This ring is composed of:
metallic fragments
silicate dust
remnant ice
Most fragments originate from the destroyed moon.
7. The Shepherd Moon
One of Hypnoth’s moons acts as a gravitational shepherd for the ring debris.
Parameters:
Parameter
Value
Orbital radius
60,000 km
Diameter
~220 km
Orbital period
17 hours
The Shepherd moon stabilizes the inner ring.
It is visible from Hypnoth as a small but bright moving body.
8. The Irregular Moon
The outer moon of Hypnoth follows an elliptical orbit.
Parameter
Value
Orbital radius
~250,000 km
Orbital period
~10.5 days
Orbital eccentricity
0.2
Its path causes noticeable changes in its brightness and apparent speed in the sky.
9. The Event Known as Shepherd’s Cut
Several times each year the Shepherd moon passes through the densest ring debris.
From Hypnoth’s surface the moon appears to:
slice through the ring arc.
This produces temporary dimming of reflected light.
The phenomenon is called:
Shepherd’s Cut
Typical frequency:
Parameter
Value
Events per year
2–4
Duration
1–3 hours
These events increase:
• micro-debris in orbit
• salvage opportunities
• navigation risk
10. Visibility of Vôrun-Hold
From Hypnoth’s surface, Vôrun-Hold appears as a small irregular object in the sky.
Angular size:
~ 0.16°
For comparison:
Object
Angular Size
Earth’s Moon from Terra
0.5°
Vôrun-Hold from Hypnoth
0.16°
Thus the Hold appears roughly one-third the size of Terra’s moon.
It is visible as:
• a dark irregular silhouette
• occasionally glinting with industrial lights
During Shadow-Shift the Hold sometimes appears as a briefly illuminated outline against the ring arc.

12. Cultural Effects
These cycles influence Hold behavior.
Examples:
Shadow-Shift is often when Kin:
• perform equipment inspection
• review operational logs
• recalibrate tools
Shepherd’s Cut increases:
• Hernkyn salvage patrols
• docking traffic
• debris monitoring
The sky itself therefore functions as:
a predictive system.
Not a symbol.
13. Civilian Observation
Kin on Hypnoth ruins or salvage crews describe the night sky as:
a pale ring across the stars
a slow wandering moon
a fast small moon
and the dark moving stone of Vôrun-Hold
Most Kin do not watch the sky for beauty.
They watch it for information.
