Pay great attention when portraying the main antagonists of the game, and make sure you stay true to their goals and motivations. Just as Fabula Ultima’s protagonists are larger-than-life heroes, their adversaries are powerful and formidable individuals, who often conceal terrible secrets. Do your best to always portray their looming threat and keep the pressure high!
When playing the game, pay attention to what everybody else is saying and encourage everyone to play an active role: each participant should get their time in the spotlight. Do your best to cooperate with everyone else and make sure the play environment is enjoyable and welcoming.
Never force the Players’ hand, and make sure not to “push” them towards a specific event: let their actions and objectives guide you instead. Resist the temptation to create a predetermined plot — let the heroes’ choices and actions tell you what aspects of the story the Players really care about.
If you're used to other RPGs in which the Game Master controls the evolution of the story and prepares scenes ahead of time, let go of that when playing this game — here, you must only weave situations around what the Players decide to do and add details to the world as required by the circumstances. The game gives them plenty of tools to influence and shape the story, up to and including the ability to alter plot elements you had previously introduced. Embrace this creative flow!
Move the action forward by asking questions to everyone else. For example: What will you do now? Where can you find this information? How do you feel about what happened? Are you willing to risk your life for this? What will you tell your mother?
Ask plenty of questions, then build on the Players’ answers.
