Rogues without Tales.

Rogues without Tales.
Oh man. Discord and the Scrying ritual makes me want a SWM ritual for an out-of-game impromptu invitation to create S&S micro-fiction. Something like a micro-rogue's phase challenge that people can invite and offer others (or play solo) in a setting like the Discord chat, G+ community, or casual conversation. Not even a scene, more like a single evocative in-character moment that one or more people can explore. Basically a spotlight, nearly context-less motif, or raw S&S cover art as a poster with a story but not a tale.

What are the minimum mechanics/structure necessary for empowering cool on-the-go micro-fiction? Should dice or a similar simulacrum set a tone for the reply or is that cumbersome/limiting? How should/could such a thing invite communal participation/affirmation and tie into other rituals and game modes in the SWM ecosystem?

How about this as a starter draft:
The Ritual of the Pregnant Moment
Share an eidolon for any ephemeral Moment you want to wrap in a shred of fictional flesh. Then direct a loaded challenge illuminated by the eidolon to a willing companion (or yourself) in the following form: "Who can show us an [adjective] rogue... [doing something]?" The challenge can be open or directed toward a specific person.

Whoever dares answer the challenge should roll dice to set a tone, and offer an incisive reply in the rolled tone, perhaps as the internal monologue of the rogue in question. Others may offer alternate responses. After a response, anybody else present may ... [?]

"Who can show us a blood-smeared rogue... wrestling with destiny" "Who can show us a sympathetic rogue... suffering for their irreverence." "Who can show us a famously brutal rogue... showing tenderness?" "Who can show us a broken rogue... wielding power."

(Embrace a pregnant pause between the described rogue and the task demanded, especially when the two deliciously contrast.)
