5MW RPG: Sectors, Serpents, and Gameplay Phases

Sectors contain one or many Systems. Systems consist of one or more stars, brown dwarfs, or black holes, and their orbiting bodies which always includes at least one World.

Sectors

Sectors are groups of Systems connected through hyperspace. Systems within the same Sector are not necessarily physical astronomical neighbors, but are spacetime is folded such as the Jumps required between them are “shorter” in practice. Sectors are depicted in game as hex map segments called Sector Segments.

Sector Segments take sizes between a single System up to ten Systems. Avatars construct their own starmaps in 5MW, placing their Sector Segments on a larger, empty hexmap, weaving their own tapestry of Sectors as they explore the 5 Million Worlds.

The idea here is that the frontier is always unknown, and that folks can build their own independent Sectors to plug-and-play as needed.

Systems

Star systems—whether a solitary star, multiple star system, brown dwarf or black hole—is called a System. Systems are often named [Star]-Sys or [World]-Sys, e.g. Spindle-Sys, Breq-Sys, etc. This abbreviation is common, e.g. in-Sys travel, out-Sys trading, etc.

Each Sys contains at least one World and one Ansible. A System, its Worlds, and other major orbital bodies are represented on a System Map: 

From the Mothership Search & Rescue Campaign post 

Worlds

A World is an orbital body where people live. This may be a planet, moon, asteroid, space station, superstructure, etc. Depending on their Form, some Avatars may need to make a Body Save against World Shock when visiting certain Worlds.

World Maps can be acquired through a World’s organization, or a close orbit scan with consent from the World’s peoples.

World Shock

Ecologies and 

Ansibles

Ansibles are the single ubiquitous remnant of the Serpents: superluminal communication nodes. From an Ansible, any Sys can communicate with another Ansible within its network in real time. Fully functional Ansibles can even use the Uplink to travel between systems, uploading the Mind and printing a new body at the System destination. Most Ansibles, however, are either derelict, thought lost, or controlled by a World’s power to disseminate or control information across the Sector.

Serpents & Serpentware

Extremely few in the 5 Million Worlds know what Serpents were/are, but their proximity to the Avatars is widespread, whether as myth, spacer tales, or historical or archaeological “fact”. Many cultures blame Serpents for the constant disappearances of large-scale Artificial Minds, Hive Minds, and other forms of superintelligence.

Serpents were/are capable of creating technology beyond the ability of any culture in 5MW Space to fabricate, and left remnants of these feats behind: superstructures and Serpentware, as well as two loose orders: the Serpent’s Lance and the Avatars.

Serpentware

While reproducing Serpentware is nigh-impossible, those with the necessary Skills and resources can repair and maintain this technology. Repairs of superstructure habitats, and the teaching of these methods, is common work for Avatars.

Other Serpentware ranges from personal equipment to starship components.

Serpentware Repairs

Serpentware almost always exists as part of a larger technological system. If Serpentware needs repairing, other Serpent ruins are very likely to be within the same System. Salvaging without permission is frowned upon, but sometimes skipped in pressing crises. Usable salvage for fixing Serpentware is counted in units called Remnants.

When maintenance requires newly fabricated components, an Avatar must use a Serpent Forge. Such incredible replication machines are found within superstructures, and very infrequently anywhere else.

Chrysalis

A Chrysalis is Serpentware whose main function is an advanced cryopod for unshielded Jumps through hyperspace. Their advanced functions include: healing pod, downloading a Mind, bio-print new bodies, and collecting a library of Forms for the Avatars to change between. A Chrysalis requires expending Exotic Matter to perform a single advanced function, and must have a hardwire connection to an Ansible.

Personal Serpentware

Highly advanced cyberware, bioware, personal protection, and other equipment also exists throughout the 5 Million Worlds. Yet Serpentware rarely exists in a vacuum; it serves its location, and holds importance to the peoples of its World. Such treasures belong to the World and its cultures, not those who find them. How the Avatars handle such encounters is important for their reputation.

Serpent’s Lance

Hunters who seek Avatars who have broken the Code, their promise to help. Members of the Lance are often former Avatars, with advanced starships and Serpentware. The Lance is not immune to corruption or transmuted belief systems.

Call of the Avatar

Avatars are mediators, liberators, merchants, explorers, and troubleshooters. They answer the Call of the Avatar to fight for peace, resolve crises, and help the peoples of the 5 Million Worlds. This is the Avatar’s pledge. Breaking this pledge may attract the ire of the Serpent’s Lance; Following this pledge may attract the ire of local Sector powers. The lives and adventure of Avatars tend to follow this pattern:

Starfaring Phase

The Avatars choose where to travel. They may begin with a small Sector map, or must find an Ansible to discover local hyperlanes.

In order to Jump to another system, Avatars must have a Jump Drive or better.* Out of respect for privacy and local traffic safety, Jump Points tend to be on the polar stellar axis of a System. Jumping elsewhere in a System is possible, with the relevant Skills, but often attracts major disfavor with space-faring locals.

Avatars may spend one unit of Exotic Matter and two weeks per light year, if they have a vessel capable of such stocking capacity, and the Warden is so inclined to build out a Realspace star map.

Avatars may begin with a small starship capable of superluminal travel called a Wedge.

Wedge

  1. Airlock with Docking Sleeve.
  2. Lander Bay. Contains one Lander Pod to travel to and from Worlds without their own travel infrastructure.
  3. Bridge. Piloting, Comms, Sensors.
  4. Commons. Bunks and central living space.
  5. Cryobay. 10 cryopods.
  6. Engines. Jump-I Drive for hyperspace travel (expends one unit of Exotic Matter per single hex Jump), and Loop-I Drive for in-system superluminal travel (expends one unit of Exotic Matter per three in-Sys uses).

Contact Phase

While contacting the peoples of a World when entering a System is technically optional, it is the done thing. Space pirates and warlords never call ahead, so Contact is common courtesy, and achieved across two steps: Ansible Ping and World Ping.

1) Ansible Ping

Avatars may attempt to ping the local System’s Ansible. If the Ansible is online, the Avatars can contact those who run the Ansible, even if only the Ansible's Virtual Intelligence that remains. If the Ansible is offline, they may skip to the World Ping and attempt to discover the Ansible’s location in the Looping Phase.

2) World Ping

Avatars may attempt to directly ping a local System’s Worlds. This may be necessary to contact peoples who do not control their Ansible, whether due to power or technological struggles. Such communications can be more easily hidden or obfuscated.

If neither pings yields results or the Avatars skip Contact, move into the Looping Phase.

Looping Phase

During the Looping Phase, the Avatars’ starship enters the standard stellar orbit. Except under unusual circumstances, a starship’s sensors can deliver a System map. Detailed information on planetary bodies, or World maps may require travelling to the orbital body.

If the Avatars chose to skip both pings, and the System has the means to initiate Contact, they attempt to ping the Avatars during the Looping Phase. Avatars enter Contact at Disadvantage.

In-Sys Travel

Looping the Sys, Avatars may travel between orbits, collect Matter, and explore Worlds using the starship’s Loop Drive. Travelling between any two regions, regardless of distance, requires two weeks and expends one use of Exotic Matter on the starship’s Loop Drive.

Looping on Mundane momentum does not expend Exotic Matter, and takes much longer.

With a comfortable starship, Avatars may Expend Limit on projects while Looping (pg. xx).

Travelling within a System depends on the infrastructure, regulations, and other local factors. Mostly, Avatar starships have free reign to travel across the system, but in certain cases they may be required to dock their starship and use local travel infrastructure, or perform special jobs or duties to extract Matter from the System.

Whether using a World’s infrastructure or their Landing Pod, Avatars may visit a Worlds to answer the Call.

The Call Phase

This is the adventure phase of the game, and makes up for most of the play. What happens depends on the World, its Peoples, the nature of the Call, and how the Avatars choose to resolve the issue.

Search & Rescue Mothership Campaign

Loads of Mothership distress signal adventures ping out in the void, so here's a way for folks to get those to table as a cohesive string of one-shots.

Guess what chump? 

You've made it onto a Search & Rescue team. For the next three years, you're a crew member on a spaceship trawling on a patrol through three star systems. Once every six months, you'll have a chance for some Shore Leave.

Misenum, J1C-II 

THR:30 BTL:13 Autocannon 1 MDMG SYS:15 CREW:15 CRYOPODS:65.

  • Autocannon, Laser Defense System
  • Extended Cryobay: Adds 25 additional crypods per ship class.
  • Tug Clamps & Mobile Engines: Affix to derelict in EVA, only for in-system travel
Your ship has a tug engine, and an expanded cryobay for potential survivors. The Company Pays the Bills (see Shipbreaker's Toolkit, pg. 40), and during this the patrol, your crew is responsible for the maintenance and upkeep of the ship.

The Patrol Loop

Your ship, Misenum, travels on a three year patrol through three systems: Calacatta & Onyx, Bizimuth, and Agate. The Loop goes:

Calacatta > Onyx > Bizimuth > Agate > Bizimuth > Onyx > Calacatta 

Your crew spends six months on patrol, then does a Jump to the next system, takes Shore Leave there before taking off for another six month patrol. Rinse, repeat. 

During a six month tour, the Warden rolls four times on the 2d10 Distress Signals table, one roll for each three weeks in space. Before assigning rerolls as All Clear, check to see if there might be an adventure that fits a previous theme. 

While the Patrol Loop suggests taking Shore Leave at designated areas, your players could also discover pirate stations or other stop-overs to spend their time. Play it loose, let the system dynamics grow as you play.

To further flesh out some of these empty worlds, check out the Rimspace Planet Generator.

Calacatta & Onyx: Binary star system


  • Calacatta: Rich system
    • Bluewhite star
    • Cal-4: lush, terraformed world; gated 
    • Cal-5:  home hub station orbits factory and mining planet
  • Onyx: Resource-rich system
    • Orange binary star; Jump required 
    • Onyx-a: Hot Jupiter, loads of resources on moons, asteroids. 
      • Shore Leave location

Bizimuth: Chaotic young system, loads of freelancers


  • Yellowhite star
  • Biz-6: Shore Leave station, orbits ice giant.
  • Hyperdense asteroid field between Biz-6 and outer gas giant, Biz-7
  • High-impact ice debris field past Biz-7 orbit out towards captured rogue planet Biz-8
  • Biz-4: Oceanic world

Agate: Outpost system


  • Orange star
  • Agate-a, b, c: dead terrestrial worlds, each with ongoing, independent terraformation studies
  • Agate-d: Shore Leave Station, orbits superearth with microscopic life
  • Agate-e: cross-ringed gas giant, hosts a few remote research stations 

2d10 Distress Signals

Every three weeks of space travel, roll 2d10 on the following table. The sole unique entry to this one would be Cold Opening, which takes place on the PCs' own ship. If it gets rolled, save that one for after a Shore Leave when they're preparing to jump into the next system. 

2. Cold Opening
3. There is a Goblin on the Loose in Icarus Station
4. Adrift
5. Terus Maju (from Distress Signals)
6. Chiron (from Distress Signals)
7. The Logorrheum (from Terrors from the Cosmos)
9. Prevenge (from Distress Signals)
10-12. All Clear. The ship is cramped, stinky, and boring. Gain 1d5 Stress.
14. Aphrodite: Luxury Space Yacht (from Terrors from the Cosmos)
16. Firebird (from Distress Signals)
19. Argosy (from Distress Signals)
20. SIS/TR

But wait, there's more!

You could just use this for any Mothership campaign, really. Replace the entries on the table with modules you own and want to run (note the bell curve), and roll 2-3 times to generate Jobs. 

You lose the potential for ship-to-ship combat, and you'll have to do your own leg work for potential system hopping, but it works. Though in this secondary case, I'd also recommend setting a Job timer and maybe consequences for if the Job doesn't get done right so bad stuff still has a chance to turn up (à la TOMBS). 

Now that this one is done, I should get around to the Ocean Superearth and Jungle Moon campaign framework tools, too...
