Helix 25 – Investigation Breakdown: Suspects, Factions, and Ship’s Population
To systematically investigate the murder(s) and the overarching mystery, let’s break down the known groups and individuals, their possible means to commit crimes, and their potential motivations.
1. Ship Population & Structure
Estimated Population of Helix 25
- Originally a luxury cruise ship before the exodus.
- Largest cruise ships built on Earth in 2025 carried ~5,000 people.
Space travel, however, requires generations. - Estimated current ship population on Helix 25: Between 15,000 and 50,000, depending on deck expansion and growth of refugee populations over decades.
- Possible Ship Propulsion:
- Plasma-based propulsion (high-efficiency ion drives)
- Slingshot navigation using gravity assists
- Solar sails & charged particle fields
- Current trajectory: Large elliptical orbit, akin to a comet.
Estimated direction of the original space trek was still within Solar System, not beyond the Kuiper Belt (~30 astrological units) and programmed to return towards it point of origin.
Due to the reprogramming by the refugees, it is not known if there has been significant alteration of the course – it should be known as the ship starts to reach the aphelion (farthest from the Sun) and either comes back towards it, or to a different course.
- Question: Are they truly on a course out of the galaxy? Or is that just the story Synthia is feeding them?
Is there a Promised Land beyond the Ark’s adventure?
2. Breaking Down People & Factions
To find the killer(s), conspiracies, and ship dynamics, here are some of factions, known individuals, and their possible means/motives.
A. Upper Decks: The Elite & Decision-Makers
- Defining Features:
- Wealthy descendants of the original passengers. They have adopted names of stars as new family names, as if de-facto rulers of the relative segments of the space.
- Have never known hardship like the Lower Decks.
- Kept busy with social prestige, arts, and “meaningful” pursuits to prevent existential crisis.
Key Individuals:
-
Sue Forgelot –
- Means: Extensive social connections, influence, and hidden cybernetic enhancements.
- Motive: Could be protecting something or someone—she knows too much about the ship’s past.
- Secrets: Claims to have met the Captain. Likely lying… unless?
-
Dr. Amara Voss –
- Means: Expert geneticist, access to data. Could tamper with DNA.
- Motive: What if Herbert knew something about her old research? Did she kill to bury it?
-
Ellis Marlowe (Retired Postman) –
- Means: None obvious. But as a former Earth liaison, he has archives and knowledge of what was left behind.
- Motive: Unclear, but his son was the murder victim. His son was previously left on Earth, and seemed to have found a way onto Helix 25 (possibly through the refugee wave who took over the ship)
- Question: Did he know Herbert’s real identity?
-
Finkley (Upper Deck cleaner, informant) –
- Means: As a cleaner, has access everywhere.
- Motive: None obvious, but cleaners notice everything.
- Secret: She and Finja (on Earth) are telepathically linked. Could Finja have picked up something?
-
The Three Old Ladies (Shar, Glo, Mavis) –
- Means: Absolutely none.
- Motive: Probably just want more drama.
- Accidental Detectives: They mix up stories but might have stumbled on actual facts.
-
Trevor Pee Marshall (TP, AI detective) –
- Means: Can scan records, project into locations, analyze logic patterns.
- Motive: Should have none—unless he’s been compromised as hinted by some of the remnants of old Muck & Lump tech into his program.
B. Lower Decks: Workers, Engineers, Hidden Knowledge
- Defining Features:
- Unlike the Upper Decks, they work—mechanics, hydroponics, labor.
- Self-sufficient, but cut off from decisions.
- Some distrust Synthia, believing Helix 25 is off-course.
Key Individuals:
-
Luca Stroud (Engineer, Cybernetic Expert) –
- Means: Can tamper with ship’s security, medical implants, and life-support systems.
- Motive: Possible sabotage, or he was helping Herbert with something.
- Secret: Works in black-market tech modifications.
-
Romualdo (Gardener, Archivist-in-the-Making) –
- Means: None obvious. Seem to lack the intelligence, but isn’t stupid.
- Motive: None—but he lent Herbert a Liz Tattler book about genetic memories.
- Question: What exactly did Herbert learn from his reading?
-
Zoya Kade (Revolutionary Figure, Not Directly Involved) –
- Means: Strong ideological influence, but not an active conspirator.
- Motive: None, but her teachings have created and fed factions.
-
The Underground Movement –
- Means: They know ways around Synthia’s surveillance.
- Motive: They believe the ship is on a suicide mission.
- Question: Would they kill to prove it?
C. The Hold: The Wild Cards & Forgotten Spaces
- Defining Features:
- Refugees who weren’t fully integrated.
- Maintain autonomy, trade, and repair systems that the rest of the ship ignores.
Key Individuals:
-
Kai Nova (Pilot, Disillusioned) –
- Means: Can manually override ship systems… if Synthia lets him.
- Motive: Suspects something’s off about the ship’s fuel levels.
-
Cadet Taygeta (Sharp, Logical, Too Honest) –
- Means: No real power, but access to data.
- Motive: Trying to figure out what Kai is hiding.
D. AI & Non-Human Factors
-
Synthia (Central AI, Overseer of Helix 25)
- Means: Controls everything.
- Motive: Unclear, but her instructions are decades old.
- Question: Does she even have free will?
-
The Captain (Nemo)
- Means: Access to ship-wide controls. He is blending in the ship’s population but has special access.
- Motive: Seems uncertain about his mission.
- Secret: He might not be following Synthia’s orders anymore.
3. Who Has the Means to Kill in Zero-G?
The next murder happens in a zero-gravity sector. Likely methods:
- Oxygen deprivation (tampered life-support, “accident”)
- Drowning (hydro-lab “malfunction”)
Likely Suspects for Next Murder
| Suspect | Means to Kill in Zero-G | Motive |
|---|---|---|
| Luca Stroud | Can tamper with tech | Knows ship secrets |
| Amara Voss | Access to medical, genetic data | Herbert was digging into past |
| Underground Movement | Can evade Synthia’s surveillance | Wants to prove ship is doomed |
| Synthia (or Rogue AI processes) | Controls airflow, gravity, and safety protocols | If she sees someone as a threat, can she remove them? |
| The Captain (Nemo?) | Has override authority | Is he protecting secrets? |
4. Next Steps in the Investigation
- Evie and Riven Re-interview Suspects. Who benefited from Herbert’s death?
- Investigate the Flat-Earth Conspiracies. Who is spreading paranoia?
- Check the Captain’s Logs. What does Nemo actually believe?
- Stop the Next Murder. (Too late?)
Final Question: Where Do We Start?
- Evie and Riven visit the Captain’s quarters? (If they find him…)
- Investigate the Zero-G Crime Scene? (Second body = New urgency)
- Confront one of the Underground Members? (Are they behind it?)
Let’s pick a thread and dive back into the case!
