"We need to know." The light bulb above flickers. "It's been months!" A hand slams onto the table; a pencil rolls to the floor.
"I know, I know." A match comes to life. "We also need to stop the rumors." The flame ignites the contents of a pipe, a deep red smoke plumes upward. "'Experiments using Scarlet;' 'advancements in magickal weapons;' 'a flying-' Ha! Does anyone really believe these? That they-"
"It's all true." A pale hand picks up the pencil from the wooden floor. "They are the best of us; we all know that." It snaps. "But they betrayed us."

A Chapter Lost; A Lighthouse Falls, is a product that is specifically, but not only, for GMs that uses the system Candela Obscura by Darrington Press. This is a Trifold, a One-Page Assignment that can be printed (or not) which contains:
Adversaries, and some example goals to guide the GM on how they would act.
Threats, that a Circle of Investigators (Players) might encounter during this Assignment.
NPCs, for GMs to use in order to guide or oppose the Investigators.
Locations, where a plot thread might be found, an interesting encounter might occur, or death—or maybe even something worse.
Gears, that the GM might give in order to help the Investigators in this Assignment.
This is my take on a Low-Prep session; where this is the only thing you, the GM, would need at your table (or tablet). So that the Players and of course you, the GM, can focus on the Assignment at hand.
Good luck to you, Lightkeeper. And may your Investigators survive another Assignment in the future.
