Welcome to the site of Oneiros VZW, one of the oldest live action roleplay (LARP)/action roleplay associations in Belgium. We  try to offer role play events to larpend Flanders and the Netherlands, together with the bevy of events that have joined us. Since our foundation in the early 1990s by a handful of enthusiasts in their garage, we have grown into an association with several hundred members and participants. Not bad for an "obscure" hobby, right?

If you want to know more about the LARP phenomenon, you have come to the right place. Our task as a Non-Profit Association is to support and distribute LARP to as wide an audience as possible. This task includes supporting initiatives that can positively highlight role-playing in all its aspects. Check out our FAQ to learn more about what LARP is, and scroll down to see what we offer! Has your interest been aroused and do you want to take a step into one of our worlds? Feel free to contact us if you have any questions, or come along to one of the events we offer!

Hopefully see you soon, in another world!

In the world of Aether, history evolved slightly different. At the end of the 19th century, humankind worked hard for twenty years to destroy itself. Now, a generation later, it's up to you, to be the inhabitant of the fictional city of Raetsburg, to help build a better future.

Aether events are open to participants aged 18 and over. You can expect steampunk and Victorian horror with an emphasis on social conflict, intrigue and arcane mysteries.


Dreaming of Ankoria is an accessible family event where everyone is welcome. Our brave players are between the ages of 6 and 12 and are taken to the magical realm of Ankoria. There they become tough warriors, brave paladins, wise mages and cunning hunters.

Participants over the age of 12 join our team of enthusiastic extras. Children under 6 can enjoy the atmosphere when accompanied by an adult.


Rogaria is a desert world where vast expanses of sand are interspersed with rare oases where life bubbles to the surface. The fierce and proud Sha'éhel rule over the Sands given to them when the Old Masters when they departed for the stars.

Rogaria events are open to participants 18 and older. This fantasy larp is visually inspired by the historic Middle East. The game revolves around life in a nomadic caravan where both everyday threats and magical mysteries lurk behind every tarpaulin.


Angst is Oneiros’ project in Nordic larp style. Angst as a LARP is not a series in such that events do not have a continued story line. Each event stands on its own. Themes and timelines differ, as well as the type of horror and the topic played. After many years of being a dormant project, we can announce 2024 will be the year of its return with its event: Angst:Hyperphagia.

More information about the event can be found on their website.


Welcome to Heimar. A country ravaged by war and plague where four peoples live together under the strict rule of the fierce Norsemen Mannheim.

Omen events are open to participants aged 18 and over. Choose your people, and become part of the dark history.

What is LARP?

A  Live Action Role Playing Game, abbreviated to LARP or LRP (from Live Role Playing) is a form of role-playing game where participants physically portray their characters (as opposed to the more well-known tabletop role playing games such as Dungeons and Dragons or Vampire the Masquerade). The participants or players (often a few tens to hundreds) invent a “character” within the given game world, and pursue goals within a fictional setting or scenario, physically represented by props. Participants react to events as their character would, with almost all actions being improvised.

Location and game world

Depending on the game world, our events are organized in castles, stately mansions, or in forests or fields. We usually spend the night on location, but one-day events are also possible. Our game worlds can contain different genres such as fantasy (just think of Lord of the Rings, or Game of Thrones), steampunk (Jules Verne, The League of Extraordinary Gentlemen,..) or science fiction. 

Goal of the game

The game control (the “Crew”) has made up a story with mysteries and intrigue. However, players do not have a predetermined role and must improvise within the rules of the game. Because players are largely in control of what they want to achieve during a weekend and how they want to do it, it can happen that the story gets lost during an event, or even has to be rewritten due to events that the game management did not foresee. The intention is not to “win” the game, but to tell beautiful stories within the game world together.

A LARP game can be the continuation of a previous event. Then the story is also a logical continuation of the previous one, combined with the events that took place then. 


Players wear a costume that matches their character and the game world. Many LARP groups describe what a certain type of character's clothing looks like. Players can make their own clothes, or buy them from stores that specialize in stage and/or LARP costumes.

Extras often receive the necessary costumes and weapons from the organization, but this will not be the case for all LARP groups. Usually the crew is quite grateful if extras bring their own costumes.


We do LARPing for ourselves, to improvise heroic, dramatic or exciting scenes together with other participants. So there are no spectators.

Action and combat

As the A in LARP stands for action, action is often part of the game. Many LARPs (but certainly not all!) involve combat. Props made of fiberglass and foam rubber are used for this. These are available in many specialized stores. Be sure to take a look at the “weapon regulations” which can be found under the XXX tab. We fight with the necessary respect for each other, so it is not the intention that there will be any injuries.

I want to participate!

We are happy to welcome you! Take a look at the events under our range (suitable for your age), and if you have any questions, we or the project managers of the event in question can certainly help you!
