Veiled Machinations - Secret Societies in Mongoose Traveller RPG

In the vast and immersive universe of the Mongoose Traveller RPG, secret societies add intrigue, mystery, and depth to your gameplay.


These clandestine organizations, operating beneath the surface of interstellar politics and commerce, provide endless opportunities for players and Game Masters alike to explore hidden agendas, conspiracies, and covert operations. This article aims to guide you through the process of creating your own secret societies and seamlessly integrating them into your Traveller games.

To illustrate the concepts discussed, we will delve into the secretive Illuminated Circle, a fictitious secret society.

Step 1: Define the Purpose and Goals

Every secret society in your Traveller game should have a clear purpose and goals. Determine whether the society is driven by a political agenda, religious fervor, or the pursuit of arcane knowledge. The goals can be broad or specific, ranging from manipulating the galactic economy to protecting ancient artifacts.

For example, the Illuminated Circle seeks to unravel the mysteries of ancient civilizations and acquire forgotten knowledge. Their purpose is to protect and preserve the wisdom of the past and ensure it does not fall into the wrong hands. Their goals include uncovering ancient artifacts, deciphering cryptic texts, and guarding ancient sites of power.

Step 2: Establish the Structure and Hierarchy

A well-structured secret society provides a framework for its members to operate within. Define the ranks, titles, and responsibilities within the organization. Consider incorporating initiation rituals, secret codes, and unique symbols that further immerse players in the society's clandestine atmosphere.

The Illuminated Circle operates under a decentralized structure, consisting of autonomous cells spread across the galaxy. Each cell is led by a Cell Master, responsible for overseeing their specific region of operations. Members progress through various ranks, such as Seekers, Lorekeepers, and Scholars, based on their dedication and contributions to the secret society.

Step 3: Develop Beliefs and Practices

Secret societies often have distinctive beliefs, rituals, and practices that set them apart from the mainstream. These elements give depth to the society's culture and offer roleplaying opportunities for players.

The Illuminated Circle believes that ancient civilizations held advanced knowledge and technologies that could reshape the current state of the galaxy. They practice meticulous research, studying ancient texts, artifacts, and architectural remains to uncover hidden meanings. Rituals may involve meditative practices and communal study sessions to enhance their understanding.

Step 4: Create Secrets and Mysteries

The allure of secret societies lies in their hidden knowledge and enigmatic pasts. Design mysteries, conspiracy theories, and closely guarded secrets that provide a sense of discovery and intrigue for players.

The Illuminated Circle guards ancient secrets, including the existence of a mythical device known as the Arcane Keystone. This artifact is said to possess unimaginable power and the ability to unlock hidden gateways to other dimensions or lost worlds. The society's members dedicate their lives to locating and safeguarding these ancient artifacts while decoding cryptic clues left behind by their predecessors.

Step 5: Establish Influence and Reach

A secret society's impact should extend beyond its individual members. Determine how the secret society exerts its influence on the world, whether through economic manipulation, political alliances, or covert operations.

The Illuminated Circle maintains a network of contacts within academic circles, museums, and archaeological expeditions, enabling them to access valuable information and artifacts. They discreetly fund research projects and expeditions, ensuring their influence extends to the farthest reaches of the galaxy. By cultivating relationships with influential scholars, they shape the narrative around ancient history and maintain control over the dissemination of knowledge.

Step 6: Integrate Secret Society into Gameplay

Now that you have established the foundation of your secret society, it's time to integrate it seamlessly into your Traveller game. Remember to consider the following aspects:

  1. NPCs and Player Involvement: Introduce NPCs who are members of the Illuminated Circle, both as potential allies and adversaries. Offer players the opportunity to become part of the society, undertaking missions to locate artifacts or decipher ancient texts. Alternatively, they may encounter rival factions seeking to exploit the same knowledge for nefarious purposes.

  2. Missions and Campaign Hooks: Design quests that revolve around recovering lost artifacts, uncovering ancient ruins, or deciphering cryptic texts. Each mission can reveal a fragment of a larger puzzle, slowly uncovering the truth behind the society's beliefs and the powers they guard.

  3. Exploration and Discovery: Incorporate ancient ruins, hidden temples, and forgotten worlds as settings for players to explore. Allow them to uncover clues and unravel the secrets left behind by ancient civilizations. Uncovering a long-lost civilization's advanced technology or unlocking a gateway to another realm can be the climax of a thrilling adventure.

  4. Consequences and Repercussions: Highlight the potential consequences of the secret society's actions. Their successful recovery of powerful artifacts may attract the attention of rival secret societies or power-hungry individuals who seek to exploit the artifacts for their own gain. The Illuminated Circle's actions may also disrupt the delicate balance of power between governments or factions, leading to unforeseen consequences.


Secret societies add depth, mystery, and excitement to the Mongoose Traveller RPG. By following these steps and using the Illuminated Circle as an example, you can create your own secret societies, seamlessly integrating them into your games. Remember to consider the secret society's purpose, structure, beliefs, and reach, as well as its secrets and mysteries.

With careful planning and imaginative storytelling, your players will embark on thrilling adventures, uncovering the veiled machinations of the hidden world that lurks beneath the surface of the Traveller universe.
