RBF: GM's Guide

- - - - - - - - - - - - - - - - - - -

This page gives a simple and light guide to Guardians of Mystery, or GMs, wanting to run this system.

The RBF Core Priorities:

Core priorities are what all the players and GMs should focus on during the conversation that constitutes the game. Every other rule supports these.

  1. The Rangers' lives should be exciting, interesting, and vulnerable, for everyone, during each game.
  2. The game should be full of interesting dilemmas and trade-offs for the players. Conflicts can't be perfectly resolved and players should be pressed to choose what they value most.
  3. The game should be immersive, with the players exploring and the GM revealing their discoveries to them.
  4. The players should occasionally surprise the GM and the GM should occasionally surprise the players.
  5. Everyone should have a good time.

For players, there is less off-session preparation required, but players are the majority of the table and have the greatest power collectively to make it an epic experience.

Principles for RBF Players:

GMs concieve, prepare and drive the game so they have the most individual power to shape the game.

RBF Scenarios

Starter Kit Scenarios

Here are 4 starting campaign scenarios for RBF. You can roll 1d4 or choose one for your first scenario. Each campaign should run roughly 7 sessions, but can be shortened with fewer steps or expanded with additional side missions as you enjoy.

*SPOILER ALERT* ! Players, do not read the campaign details if you plan on playing!

  1. The Gangs of Nuradda

    • This urban campaign can be resolved with a variety of creative solutions.
    • On the heavily built-up and overpopulated city-moon of Nuradda, rangers investigate a tangled trail of gang wars, terrorists, mad science, rebels and C.E.O.s to solve a major conflict.
  2. Traitor's Prayer

    • This campaign focuses on the rangers as military special forces, so players with combat skills or combat psionics are a must.
    • The reptilian Horde has been conquering and exterminating world after world, but Admiral Holland has a last ditch plan to stop them. You will be assigned a wide variety of infiltration, alpha strike, and sabotage missions to take out their leaders and stop their advance.
  3. The Spiral Path

    • This campaign focuses on religion, psionics and gods in the setting.
    • Fragments around the galaxy describe an ancient evil leading to the cyclical extermination of life on a scale of millenia, and now is the time. But how can you sort between vague superstition, honest piety, grifting doomsday preachers, and true cosmic peril? And can four young rangers really hope to defeat a god?
  4. Rise of the Pyre

    • This political conspiracy campaign focuses on the rangers building support among various political factions to stop a hostile cabal.
    • Resentment for the egalitarian meritocracy of the Alliance has been boiling among the Cinterian nobility for decades. Through twisted and selfish alliances, a dark circle of would-be tyrants has hatched a plan to revive the most evil weapons once more, but exactly who is behind this is a mystery. Can you find them before the galaxy is embroiled in civil war again?

Other Settings

You can also run games in very different settings as long as you keep the same general idea of daring, vulnerable characters in science-fantasy situations.
