On the wreck of the Z15A, near the Great Plain, there are three wrecks near a large lake/sea that always attract attention. The Green, Red and Blue ships are not spaceships, but rather waterborne craft from the ship’s former life, all now rusted wrecks that will float no longer.

All three can be found in The Galleries. This area, located port-side amidships, are where the structure of the ship blends seamlessly into buildings on the Great Plains itself. Many of the transportation links into the inner world start or end here, including the docks that these ships presumably used.

The Ships

All three ships are huge – the intact hull of the Red Ship is some 1000m in length, while the less intact Green and Blue ships were estimated to be in the 750 length.

Blue Ship

The most ruined of all three ships, all that is left of the Blue Ship is half a hull rotting. Large parts of this ship have apparently been cut up over the possible centuries it has been a wreck, possibly even as far back as the original inhabitants. Most of its equipment has similarly been carefully gutted, which speaks to re-purposing.

Green Ship

The Green Ship, resting on water-sodden grass, looks to have been deliberately run aground. On its hull can be found the remnants of scaffolding and work, possibly after it was run aground.

Unlike the other two ships, the Green Ship looks to have been a pleasure craft of some sort, with many features still found on terrestrial or space cruise ships today, including many open areas and more.

Red Ship

With lines that are reminiscent of an Earth-submarine during their second great war, this ship is the most intact in some ways, as the full hull is still visible. As the seas of the Great Plain are never more than a few metres deep at most (one way we know Z15A original inhabitants were not aquatic), it is unlikely the Red Ship actually was a submarine.

Inside the Red Ship is a maze of small passageways, with some decks being less a metre in height. On the side of the ship are doors that open, possibly for launching or retrieving other craft.

The Galleries

The Galleries are the main interface between the rest of the ship and the Great Plains. While other connections exist, only in the Galleries are there big enough connections to move full small ships or big equipment into the Great Plains.

The Galleries are named mostly because of the view they give – across the Great Plain. There are hundreds of km of window overlooking the Great Plain, parts of which could be considered places to rest or stop – whether to eat or not is unknown at this point.

Main Gallery

The Main Gallery is located exactly amidships on the port side, and contains the two largest airlocks on the ship, as well as a cavernous space between the two to allow transfer of materials. The outer pairs have long been breached, leaving most of the galleries open to space. But the inner pair are both intact. Each airlock was a 1 km cube of space, allowing moving all but the largest of vehicles all the way onto the Great Plain.

Today we head back to Mephistopheles Cluster and the giant wreck of Z15A. A wrecked generation ship, Z15A is so named because of where it it is – Z sector, 15th quadrant, largest object in that quadrant, according to first Terran survey of the cluster.

Z15A has a number of notable features – it is huge (over 1000km long), it is apparently still sort of working (there is a breathable nitrogen/oxygen atmosphere in parts) and nobody really truly knows who originally built it.

Major parts of Z15A

In the thousands of rooms, corridors, bays and other spaces of Z15A, there are several that stand out as noteable.

Chi-nith-ra (Great Plain)

A massive space in the centre of the ship, the Chi-nith-ra or Great Plain more resembles a slice of a planet than the spaceship it is. Amazingly, this space retains both an atmosphere and heat, so can be walked around without a space suit.

During The Closing, inhabitants of several space stations retreated here as systems started failing on their stations. These humans and other species still squat here, despite all efforts to move them.

There are three distinct settlements within the Great Plain – New Hope is a primarily Human settlement, from the major Solar Compact station as well as few outer colonies. The Halite Commonwealth has formally accepted the small remnant of Qoss and Yishk who live in Britli-kat as part of the Commonwealth, although no other power recognizes their de-facto ownership and control over this part of the ship.

Lastly the reclusive Bredensonee, a large herbivorous species that resembles a bipedal woolly mammoth, have a large settlement in the far stern end of the plain. They are a descendants of a large family ship that was caught in the cluster due to The Closing on its was to a colony world. By far the most numerous settlement (really settlements), the Bredensonee have resisted efforts by their government to resettle them of Z15A, the suspicion amongst the others who live in Z15A is that this settlement is some type of religious order who may have fled to avoid persecution, although neither they, nor the central Bredensonsee government are saying anything.

Main Concourse

Running down the centre top of the whole ship, from above the bridge at the front to the large docking bay at the rear, the main concourse is almost all open to space.

Docking and Ship Building Bays

A big part of the external parts of Z15A comprise the many docking and ship building bays that befitted a ship of this class. Most of them are empty, possibly when the original inhabitants left the ship, but some are filled with debris and parts of starships.

In the explorations of the ship, nobody has of yet found any intact small ships, but it is possible deeper in some of the bays, beyond the debris piles, there are complete starships.

Robots and other automated beasts

While Z15A is very definitely clear of any of the original inhabitants and large parts of it are open to vacuum, the ship is far from dead. The fusion reactors or whatever power the ship still function and the energy signal is very faintly detectable. Some parts of the ship retain atmosphere and heat, notably the vast inside space known as Chi-nith-ra. There are also a fair number of smaller robots that still function, some of which can pack a fair punch.

Security Bots

The stern end of the port side, beyond some empty ship building bays is an area that is shielded and still patrolled by security bots – armed with fairly primitive but highly effect lasers as well as low-velocity slug throwers. They appear to be guarding room that is approximately 500m cubed. It is on the exterior of the ship, with a large bay door that is similarly shielded and armed. Nobody has successfully entered this area and reported back, although it is possible a stealthier mission might have penetrated the defences here.

Security bots can be found scattered throughout the rest of the ship as well, although most are inactive. They appear near what look like former weapons installations (all removed or destroyed) or in a few of the small craft hangers

Cleaning and Repair Bots

Far more numerous are the cleaning and repair bots that function in some parts of the ship. These vary in size from the size of a bread box to large vehicle size, depending on the area. Most of these are harmless, although some malfunction and their tools can be harmful or even lethal.

The Great Plain has a variety of robots that work around it – underneath in the passageways that service the ecosystem

I was going to do a piece on the Halite Commonwealth capital city today, but I thought I would detour with a stop at Sonnoros, a Saturn-like planet in the Halite system home to the intelligent Zennanesh race, a very large floating jellyfish-like species.

Native hydrogen breathers and from a gas giant, Zennanesh are the first known intelligent species of their type in the galaxy.

Sonnoros also hosts the Halite Legislature (somewhat similar to how the European Union or South Africa used to function, where the executive is hosted in a different city from the legislature)

Adventure Hooks

As most player characters aren’t capable of either flying or breathing hydrogen, adventures in Sonnoros will be limited to either the main floating stations – often mining stations for rare elements in Sonnoros’ atmosphere, or meeting points. Although the Halite Commonwealth is stable, wealthy and safe, even the richest places have their underbelly.

Players have been approached to smuggle some goods off of a mining platform. They have to move the objects across the table to the airlock (and their ship). The loading dock is busy with civilians, so lethal force is not allowed. Players must create distractions so the port police don’t notice what they are doing.

Today we turn to an odd enigma – the Mephistopheles Cloud – named for the swirling colours and massive graveyard of ships and space stations that dot the cloud.

An area of space around 1/4 of the AU across, the Mephistopheles Cloud is home to some 15 warp gates and at last catalogue, some 90 years ago, 524 individual space stations or ships, most of which are abandoned. Both Solar Compact (Earth and most of the solar system) and the Halite Commonwealth maintain active stations here, as this is a waypoint to just about anywhere else.

The mystery comes in – how did the warp gates end up here? Nearly every else that has warp gates is by a major gravitational feature – a star or something similar. It wasn’t until after The Opening that a chance discovery lead to the finding of the grooves in space. Somebody dragged every warp gate from the systems many light years around to this cloud. And that “dragging” left telltale grooves in the universe.

Adventure Hooks

1. The biggest ship here is the generation ship Z15A. Massing millions of tonnes and some 1000 km long, this is a remnant of an alien race leaving their dying sun.

Players are tasked with retrieving a lost scavenger party. The ship retains power through fusion generators, so many of the automated systems are still active. Foes include sentry robots and automated cannons, while stasis traps catch the unwary.

Like a fool, I (Corey) am throwing myself into #dungeon23 to build a galaxy for my upcoming Sellswords & Spellslingers scifi rulset. I’ll be creating a planet or so a week, with locations added each day

Hicanede

Today we visit, Hicanede, a mining colony famous for its incredible snowstorms and deep orange sky. The planet is incredibly rich in minerals that are rare elsewhere, and most of those deposits are easily accessible right below the surface. Massive open pit mines dot the planet, some recent and still being worked, others abandoned at various stages, including some after The Closing (the event when most warp gates closed at the same time)

Adventure hook

Strange radio transmissions have been received from a long-closed mine. Players will need to investigate it. The mine was abandoned well before the Closing, but has been worked intermittently since then.

Foes include corrupted zombies, potentially also including a rival salvage crew.

The Closing (added Jan 3rd)

Travel in our galaxy involves using warp gates – instantaneous travel between linked pairs of gates, usually in solar systems. Most of these gates can be found in the 5 to 10 AU range from the star (between Jupiter and Saturn), although they have been found inside stars and scattered throughout the galaxy.

The event now known as The Closing actually began about 10 years before the event itself, as astrocartographers began noticing gates fluctuating and blinking on and off, initially seemingly at random.

A year or so before the closing, the blinking began happening consistently, each gate closing for 48.61 minutes at a time. The discovery that this was 1/1200 of the rotation time of the pulsar X-45JB was discovered by the AIs at the Martian National Radio Observatory, observing this strange pulsar with an orbital period of days rather than seconds.

The Closing is now known to have begun with X-45JB stopping for a full rotational cycle. At that very moment, around 75% of all gates shut. And stayed shut, for nearly 75 years. The chaos this caused is incalculable. Billions are believed to have died in the upheaval that followed, as stellar nations suddenly became chopped apart. Many newly settled worlds failed, as the lack of new people and resources meant they didn’t come.

And then, just like they closed, the gates reopened. It is now 3 years since that event and people and ships are flooding through the reopened gates. Alliances and wars are being fought over territory, while many planets are still as of yet officially unrecontacted.

Adventure Hooks

Just about any type of adventure is possible now. Earth and the Solar System, long self-sufficient, weathered the closing well. Charismatic leadership kept the Solar System intact as a single political body. Similarly, the Halite Commonwealth got extremely lucky – only 1 of the 5 gates for their main planets of Speibahi and Dreglo shut, meaning they expanded quickly. However, hundreds of other planets exist in states from totally uninhabited through to struggling with pre-warp or pre-space tech.
