In the far-reaches of space, there drifts a colossal unmanned manufactory, shaped like a sword. None know the true origins of the vessel, but it is posited that some ancient alien race built the factory and its rules to act as judge and jury for their home planet. The ship has an impartial A.I. that judges the actions of sentient life-forms it encounters. Then, if it senses any impropriety, it dispenses its executioners. Automatons are constructed to severely punish those who the ship deems reprehensible. However, the A.I. is inordinately harsh in its rulings. So much, in fact, that many think this spelled the fate of the original creators of the A.I. The Celestial Tribunal has acted thusly for millennia. If it finds its way into your galaxy, or if you find yourself in the range of its scanners, be prepared for a harsh sentence. This is a mini-expanion and pre-order bonus for Sentinels of the Multiverse: Villains of the Multiverse.
Sentinels of the Multiverse: The Celestial Tribunal Environment supports 2–5 players according to the catalogue. This range comes from the publisher’s listed player count, so the game can be set up for any group size within it. Some setups, rules and scoring details may still vary by player count, so check your edition’s rulebook for the exact configuration.
The listed playing time for Sentinels of the Multiverse: The Celestial Tribunal Environment is 30–60 minutes. This is the publisher’s estimate for a full game. The actual duration depends on the group, the player count and familiarity with the rules: first sessions usually run longer, while experienced groups often finish faster. Setup and teaching time are not included in this estimate.
The catalogue lists Sentinels of the Multiverse: The Celestial Tribunal Environment for ages 8 and up. This is the publisher’s recommendation and reflects reading demands, rule complexity and small components rather than theme alone. Younger players can often join with help from an adult, so check the age guidance on your edition and consider your group’s experience with board games.
Sentinels of the Multiverse: The Celestial Tribunal Environment has a complexity rating of 2.0 out of 5 from BoardGameGeek players, which makes it a medium-light game.
