Week 3 Studio: Truth and antagonist

Fusing your premise with a concrete Mythos entity or faction, and stating the causal truth your whole scenario hangs on.

8 March 2027

A premise is a mood; a truth is a mechanism. This studio is about picking one specific Mythos entity or faction and fusing it with your premise until you can state, in one causal chain, what actually happened and what happens next. A modern conspiracy story fused with an existing Mythos race, or a personal object fused with a specific Great Old One’s cult, are both the same move: borrow the unfamiliar half from the Mythos, keep the familiar half from your own premise.

Blase’s scenario design guide (source #5) frames this as starting from a question, not a plot: “Which Outer God is behind this?” is too Mythos-forward to build a truth on, but “why did the astronomer destroy their own telescope?” is concrete enough to answer. If your premise doesn’t yet suggest a question a stranger would want answered, that’s a sign the truth isn’t ready to write. Once you have a question, Blase’s “hidden truth” is a sharper version of the causal chain this studio asks for — the Keeper’s answer key, written as six questions: what happened before play, what the antagonist wants, what they’re doing right now, what they fear or need to hide, what makes the threat unnatural or horrific, and what could change the outcome. Answering all six is a stronger test than the goal → past action → next step → consequence chain alone, and it’s worth explicitly separating what a cultist believes they’re doing from what’s actually true — the gap between the two is often where a scenario’s best twist lives.

Before the session#

Skim two or three Mythos entities or factions you don’t already know well. You’re looking for one that answers a question your premise raises, not the most famous option.

In the session#

Write your truth as: goal → past action → next step → consequence if unopposed. Read it aloud to a partner without any other context — if they can’t repeat back what the antagonist wants, the chain isn’t causal yet, it’s still mood.

Afterwards#

The Scenario Pitch (due this week) is exactly this: premise, antagonist, truth, and the horror and player experience you intend. Submit it before moving on to structure.
