Marduk System
If corruption and greed were given a home, Letheon Black would be the place for it. From illegal enterprises for fortune or fame, to degredation of the human spirit, this is the place for it.

Jumpgate Status: Locked
Government: Syndicate Run
Significance: The Marduk System is controlled by the Octavion Syndicate much like Letheon Black. Marduk is the home of the Mansion.
Star: Marduk
Star Type: K‑Type Main Sequence (K2–K4 V) A stable, long‑lived orange dwarf. Slightly cooler and dimmer than a G‑type like Aureleth, but still excellent for supporting habitable zones.
Color: Warm orange‑gold
Luminosity: About 0.4–0.7× that of Sol. Bright enough to sustain life, but with a softer, more amber light.
Behavior:
Extremely stable, with minimal solar flaring.
Long lifespan, giving the system billions of years of predictable conditions.
Creates long, warm seasons on planets in its habitable zone.
Its orange light gives the system a distinctive amber hue, especially during dawns and eclipses.
Star: Anu
Star Type: M‑Type Red Dwarf (M5–M7 V) Dim, cool, and small but active.
Color: Deep crimson‑red, almost blood‑red during close passes.
Luminosity: Only 0.01–0.03× that of Sol. Barely contributes heat or light except during close orbital alignments.
Behavior:
Highly active, prone to small but frequent flares.
Moves in a tight, eccentric orbit around Marduk, causing periodic alignments.
Creates dramatic red‑tinged eclipses when it passes between Marduk and the planets.
Its gravitational influence subtly distorts planetary orbits, creating long‑term cycles and rare celestial events.
Planets
Nergal
Type: Tidally locked terrestrial
Position: Innermost planet
Atmosphere: Thin, ionized, unstable
Description
Nergal is so close to Marduk and Anu that its dayside is a molten hellscape.
Dayside: molten rock seas, superheated atmosphere, constant solar bombardment
Nightside: frozen basalt plains, no sunlight, no atmosphere circulation
Hazards
Surface temperatures swing from +1200°C to –200°C
Solar storms from Anu strip atmosphere continuously
No life, no terraforming potential
Significance
Used only for:
extreme solar research
radiation‑hardening tests
Syndicate weapon stress trials
Shamash
Type: Hot desert terrestrial
Atmosphere: Thick, dry, silica‑laden
Description
Shamash is a world of endless dunes, glass plains, and superheated winds.
Temperatures regularly exceed 60–70°C
Sandstorms can last weeks
Occasional volcanic activity
Hazards
Silica storms that shred equipment
Heatstroke risk even with suits
Unstable magnetic field
Significance
Syndicate uses it for survival training
Illegal mining of rare heat‑formed crystals
Rumored to host hidden Syndicate caches
Irkalla
Type: Terraformed terrestrial
Atmosphere: Earth‑like
Native Life: Various plant life and animal life native to the planet.
Surface: Plains, engineered waterways, controlled climate, multiple terraced structures left by previous residents
Description
Irkalla was previously inhabited by a previous civilization, leaving behind traces of their society.
The archaeological expedition is researching this now missing species. What they’ve found is that the previous Irkallans were at least 15 feet tall and crustacean-like in appearance. They’re assumed to have left the planet millennia ago, as there are no signs of mass extinction.

· Various rivers, lakes, and artificial waterways to control flooding
· Controlled weather systems
· There are terraced structures throughout the world with chambers inside the terraced structured
Hazards
· The Mansion complex
· Hidden underground transport tunnels
· Surveillance systems woven into the biosphere
· “Hunting grounds” disguised as nature preserves
Significance
· Center of Syndicate entertainment, torture, and slavery
· Mansion is the largest structure on the planet
· Ganzir (anarchist community) exists on the outskirts
· Many discarded slaves flee here and form hidden settlements
Ninurta
Type: Rocky super‑Earth

Description
· Ninurta is a massive, mineral‑rich world with brutal gravity.
· Jagged mountain ranges
· Deep metallic canyons
· Constant seismic activity
Hazards
· High gravity crushes unaugmented visitors
· Frequent quakes
· Toxic dust storms
Significance
· Syndicate’s largest mining world
· Produces metals used in cybernetics, weapons, and ship hulls
· Workers are often indentured or enslaved
Enlil
Type: Gas giant
Atmosphere: Hydrogen, helium, exotic gases
Moons: Several small mining outposts
Description
· Enlil is a massive gas giant with swirling amber and blue bands.
· Strong magnetic field
· Violent jet streams
· Deep atmospheric vortices
Hazards
· Lightning storms thousands of kilometers long
· Pressure zones that crush mining rigs
· Radiation belts
Significance
· Primary source of energy for the Marduk system
· Helium‑3 extraction
· Syndicate controls all mining rights
Adad
Type: Storm world Atmosphere: Hyperdense, electrically active
Description
· Adad is a world of perpetual storms.
· Global hurricane systems
· Lightning arcs visible from orbit
· Oceans churned into vapor by constant heat
Hazards
· No stable land
· Storms reach Category 7+ equivalents
· Atmospheric pressure lethal to humans
Significance
· Used for atmospheric research
· Syndicate tests weather‑based weapons here
· Rumored to hide storm‑powered generators
Tiamat
Type: Ocean super‑Earth
Atmosphere: Thick, humid
Surface: 98% water
Description
· Tiamat is a massive water world with:
· Deep global oceans
· Floating archipelagos
· Towering storm fronts
· Bioluminescent algae imported from Tsovinar
Hazards
· Megastorms
· Rogue waves kilometers high
· Pressure zones that crush submersibles
Significance
· Syndicate uses it for aquatic training
· Illegal underwater labs rumored beneath the surface
· Some escaped Mansion slaves hide on floating debris islands
Ereshkigal
Type: Frozen outer world
Atmosphere: Thin nitrogen‑methane
Surface: Ice plains, cryovolcanoes
Description
Ereshkigal is the coldest world in the system.
· Temperatures near –180°C
· Cryovolcanic eruptions of methane and ammonia
· Long, dark winters due to Anu’s orbit
