Welcome to the SevCol Website!

This is the website for the SevCol LARP. SevCol is a Live Action Roleplaying Game, which takes place on a spaceship around the year 2180, travelling through the solar system (and beyond). To create this spaceship, various simulation software will be used, and extended with all sorts of hardware to create an immersive space travel experience. SevCol aims to be a ‘rule-lite’ LARP; using very few rules, and focusing on immersion and character play.

SevCol 16: The Green Hills of Earth

Dear crew members, ship security, specialists and passengers, SevCol is proud to present its first on-site role-play event of 2022: SevCol 16: The Green Hills of Earth, on the 7th, 8th and 9th of Oktober.

We have planned another on-planet event, and thus we will use the Scouting terrain of Skoltaro in Eibergen again.

We will start the larp on Friday evening. This would mean time for socializing with your fellow larpers, and helping us with preparations. It will also allow you to be on time for the early start on Saturday.


The Celestra heads towards Earth to finally visit the blue planet, after receiving their invitation to compete in the finale of the Universal Challenge! Crew members of the Celestra have earned their place in the final rounds of this Earth-based game-show by competing in a regional challenge, and now the whole crew has been invited to visit the New California studio complex on Earth. The Celestra crew has arranged some other ‘exclusive sight-seeing tours’ near New San Francisco to make the best of their time on Earth, so now everyone is preparing for this undoubtedly eventful trip! The crew hopes to finally find some clues to the whereabouts of the elusive Mr E while they are travelling the west coast, and get an opportunity to put a stop to the evil schemes exacerbating the political situation in the Solar system.

SevCol Online 4 – Dark Side of the Moon

Dear crewmembers, ship security, specialists and passengers, SevCol is proud to present its first role-play event of 2022: SevCol online 4: Dark Side of the Moon.

This will be our fourth online event. This event will still be entirely within Discord, and once again, it will take place aboard the Celestra.

The larp will take place on Saturday March 26th, starting at 10:00, and continuing (with a soft ending) at around 17:00 or earlier. We will have an in-character break around noon, during which everyone is free to take a break with or without turning their camera off, and having lunch.


On request of SevCol, the Celestra travels to Luna to quell unrest brewing in the colony. Protests and riots are breaking out on the Lunar surface, and recently, important space stations around Luna have been rendered out of commission by striking personnel. The Celestra crew has been in contact with many important factions in the colony, and might assist in reaching a solution.

This is Burne Thompson for 6-News. We are sorry to interrupt your regular stream, but our communication from our reporter May O’Neil was interrupted and the signal lost. We take you to the official government broadcast from Geneva Dome to report on the proceedings between the Mars Volunteers and Union. We take you live to Geneva Dome.

An unknown event has caused catastrophic pressure loss and damage in Geneva Dome. If you are within a pressure-shelter, remain in place, otherwise proceed to a disaster shelter immediately.

This is Burne Thompson for 6-News. There seems to have been some sort of accident that has… Wait… We are recieving an unconfirmed report that Volunteer forces have deployed some kind of non-standard explosive weapon in an attack on Geneva Dome. They claim to have struck back at their opressive… Sorry, no, we have unconfirmed reports that Union radicals are responsible for the attack as well.

Both parties are currently claiming to be behind an attack on Geneva Dome on Mars, which seems to have caused catastrophic damage to the buildings and structure of the dome itself. Orbital observation reports a bright flash, followed by a shockwave and large cloud forming over the dome. We will update you as the situation develops.

The Martian supercomputer should not be trusted!

At this, the 13th of March, 2181, our independent journalists bring you this news!

As the situation on Mars grows more turbulent/dire, the Martian supercomputer is still spewing out nonsensical commands which confuses and divides the Mars populace even further! As usual, leaders of the domes allied with the Martian Union still trust the supercomputer commands and blindly follow its instructions without any doubt or critique, while the logic of these commands appears to deteriorate with each passing day. Just this afternoon (at approximately 12:30) most Union dome residents were seen doing some sort of yoga poses outside of their homes and offices, seemingly undisturbed by the fact that chaos and terror is currently reigning in the colony!

The Martian Union will not hesitate to tell you that the Supercomputer’s directions is what’s keeping the colony stable and thriving, but is this still the case? Is the computer and its enigmatic algorithms still reliable, even after all these years of governing the colony? Isn’t it possible (or maybe even likely) that a supercomputer like this might develop bugs or glitches over time?

Of course, none of the residents of this beautiful red planet wants to see the colony fall into ruin. However, descending into chaos might exactly be the path we’re on, if we keep following the supercomputer’s bizarre instructions. Union leaders would be wise to critically look at the commands they’ll so obtusely accept into their daily routines, and wonder whether these orders will actually contribute to the prosperity of colony and the wellbeing of the dome’s residents.

So, has the Martian computer gone haywire? Or are the Martian civil servants just too incompetent to properly interpret its output? We leave you to make up your own minds about this situation.

New Revelations about the Red Conspiracy and the Celestra!

Readers diligently following this channel of AWARENESS & TRUTH will undoubtedly remember the heroic mr Madsen who single-handedly arrested the terrorist leader Andrea Enslin! Madsen had briefly joined the crew of the controversial starship Celestra, but after discovering the terrorist hiding out on this ship (seemingly with permission of the rest of the crew), he was quick to arrest her and to distance himself from this nefarious crew!

Mr Madsen has now revealed some VERY disturbing news about the hidden forces behind the unnerving current events flooding our newsfeeds! We received a video in which he theorizes about the powers driving the chaos unfolding within the solar system and beyond, and reveals some very disturbing facts about the ‘Red Conspiracy’, and its connection to the Celestra! The speculations of this astute man are most likely on the right track, since he has undoubtedly proven he can indeed trust his instincts in matters like these! Mr Madsen also mentions the enigmatic ‘Mr. E’, who seems to be intricately connected to this whole conspiracy! Mr E was previously discovered – by our very own star-reporter Killian Robertson – to be the very owner or the Celestra!

SevCol 15: This was a Triumph

Dear crew members, ship security, specialists and passengers, SevCol is proud to present its first on-site role-play event of 2021 (and 2020): SevCol 15: This was a Triumph, on the 25th and 26th of September!

We have found a cool new location which we will put to the test with this event! This does mean that we cannot sleep on site, and as such we can provide sleeping arrangements with other players and organizers living nearby.

We will start the larp on Saturday, but we offer the option to arrive on Friday evening. This would mean time for socializing with your fellow larpers, help for us with preparations, and possibly time for simulator practice. It will also allow you to be on time for the early start on Saturday.

The event will only take place if the then-current Covid regulations allow multi-day events without a 1.5m social distancing rule and without mandatory face-masks. You are of course allowed to practice any personal safety measures you want. We do urge people to please register if you plan to come, and register early. Both for the peace of mind for us as organisers, and so that we will not have to cancel the event due to a lack of interest.


The Celestra has completed its tasks in Alpha Centauri and has traveled back to the Solar System. It is about to dock at SevCol station after a small delay (or two…). The news reports and messages that have reached the crew so far seem to be troubling, both on a personal level as well as on an interplanetary level. What new mission will there be for the Celestra, and how will the situation on Mars develop?

SNN Special Report – Census Bureau Mars Situation Findings Published

By Johnson Frederick on March 12th, 2181

This is Johnson Frederick with the latest results of the SevCol-requested and financed study into the possible effects on the economy and living conditions on Mars, in the event of roughly half the population no longer following the Mars’ computers directives.

As you are all no doubt aware, that is one of the likely scenarios as a result of the current disagreements on Mars. Some specialists argued that there would be negligible effect, as experienced individuals would continue to do the job and do what’s needed. Other experts pointed to the delicate balance of each individual dome, and the even more fragile ecosystem of all domes combined. Coupled with time-critical and for humans, hard to predict but required actions, these experts predicted a partial or complete collapse of the economy and possibly even society on Mars.

With predictions amongst experts varying so wildly, the world of predictive experts was shocked roughly a week ago, when Jeans James, a PhD at Luna university, presented a paper with the results of adapting his predictive model for bacteria growth in semi-joined vessels, to the situation in Mars. This model was unique, in that none of the experts at the time could find a fault with its method. Hence, the results were of special interest, but mister Jeans, upon the request of SevCol, postponed the results of his findings. SevCol requested this due to the volatile nature of the current situation, and promised to spare no effort in going over this model and improving upon it, letting the Census Bureau work alongside mister James, throughout the week.

Some have reported that work on the model has been going on for 24 hours a day for the last six days, with many of the mathematicians and statisticians working well into the night, working in shifts, and running the simulation on well over a thousand computers at once.

The results of these simulations have now been published, with the caveat that peer review is currently ongoing.

The results of the preliminary, limited model of Jeans James predicted a partial societal collapse, with an almost complete collapse of the economy, and a partial collapse of society. Recovery of the society would take 20 years +/- 15 years, and the economic recovery would take 30 years +/- 40 years. This result was interesting, but as you can see, the uncertainty of the results were rather high.

The improved model came up with somewhat more precise results, as well as separate results for each of the Mars’ domes. The results for each dome will be published after more model and peer review, as the results have a lower certainty, but the overall results were estimated to be ready for public consumption.

The Census James’ Model for Mars’ Running With 50% Separated From The Mars Computer (name still being workshopped) estimates that the impact on the Mars’ domes will be severe. It shows an almost immediate decrease in efficiency in all of the domes, leading to a decrease in production, leading to a sharp decline in economic power for all of the domes. THis decrease in efficiency could be brought back to roughly 85% of current in 5 to 10 years, assuming competent leadership. This is for the domes choosing to go independent of the Mars’ Computer. The domes trying to follow the directives of this computer are far worse off, with a recovery time estimated to be well over 40 years if they continue to follow the computers’ directives.

The effects of the increase in weird directives from the computer has so far not been studied, but a preliminary probe by the Census Bureau into the possible effects have shown that although the effects of these weird directives are currently likely negligible, the amount of directives is experiencing a steady growth. If they start to interfere or replace the ‘ useful’ directives, this could well start leading to a measurable decrease in efficiency.

SevCol has so far declined to comment, stating that these results bear careful consideration, and that an official statement from SevCol will follow in a day or two.

Lastly, due to popular request, the Census Bureau has created a process for the Mars’ domes to request and receive the predicted effects for their dome, as long as a contract is signed, stating the knowledge of the receiver of the inherent uncertainties of such a model on such a reduced scale.

SevCol Online 3 – Return from the Stars

Dear crewmembers, ship security, specialists and passengers, SevCol is proud to present its second role-play event of 2021: SevCol Online 3 – Return from the Stars.

This will be our third online event. This event will still be entirely within Discord, and once again, it will take place aboard the Celestra.

The larp will take place on Saturday April 17th, starting at 10:00, and continuing (with a soft ending) at around 17:00 or earlier. There will be a 30-60 minute period of no plot for lunch at around noon.


After an almost uneventful journey, the Celestra arrives in the Solar System. Many news reports have already reached the crew about the state of the colonies in the Solar System. The long journey to SevCol station, orbiting between Earth and Luna, allows plenty of time to catch up on current affairs. The Celestra’s course will take it past most colonies in the Solar System, allowing for real-time communication between friends, relatives and other contacts.
