Try Flashbacks For Backstories
The first time I encountered a flashback mechanic was at Intrigue Con here in town in a Night’s Black Agents game. The second time was the following morning playing Blades in the Dark.
The cool thing about flashbacks is you can add them to any game system. I’m doing it right now for my Lost Isle D&D 5.5 campaign, for example.
If you haven’t used flashbacks before, that’s what I want to noodle about with you today.

What’s a Flashback?
A flashback is a narrative tool. The way I use it, it needs no rules or setting integration.
Instead, a flashback lets you tell a tiny story about the past to explain the present.
In The Lost Isle, I’m using it to bootstrap character backstories into play:
Is there anything in your past you could apply to solve this right now?

Why Bother?
From past campaign experience, I’ve found players introduce great new NPCs, locations, and items this way, which I drop into quick session log entries for later development.
Then, during prep, my sneaky tactic is to start connecting the game pieces together.
This serves up great discovery and roleplay moments when players uncover these secret links.
It also retroactively bonds characters together – even those “I’m an orphan who knows nobody” pesky PCs. This helps party cohesion and teamwork.
Stuff players invent that I don’t connect to other characters get connected instead to the villain, milieu, or both.
For example, a new dwarven clan mentioned by name in play gets enfactionated by yours truly. Or a magic wand the wizard stole in his youth then taken from him is now being wielded by a BBEG lieutenant.

GM Levers
I’d classify myself as a controller GM who doesn’t like big new elements being added to settings and campaigns by players. Is this old school? Not sure.
I develop a strong vision for my settings and plots. And I don’t like trying to fit rando square ideas into my round plot holes, haha.
Flashbacks seem to gel well with me, though, despite my predisposition to manage all the secrets.
For starters, I couch flashbacks as character memories. And memories are fallible.
So players aren’t introducing canon. I decide what the game pieces truly are if they don’t match my ideas or campaign needs.
For example, the dwarven clan might be outcasts and don’t get a seat at the big council I’ve carefully plotted out. And the wand might be cursed, fake, or even more powerful than recalled.
Flashbacks also let us retcon stuff with a bit of grace. When the past’s changeable, the present can be reframed.
Finally, players get attached to what they create. Instant engagement.

It’s Your Turn
In Blades in the Dark and Night’s Black Agents, you can use flashbacks to explain why you’ve suddenly got the perfect piece of gear or key knowledge.
I don’t go this far with my use. It’s more for roleplay and flavour that dovetails into worldbuilding.
If considering this tool for your campaign, think about what boundaries to set that would work for your GMing style.
For example, can players invoke whole new continents, kingdoms, and villains? Or just the small stuff as is my preference?
Then explain to your group and try it out.

Want to Take This Further?
If you’re struggling with session prep that actually survives contact with your players, you will love The GM’s Log.
Every week, you get a PDF that breaks down a specific method like flashbacks with step-by-step guidance on how to use it.
The GM’s Log shows you how to build stronger encounters, smarter villains, and more responsive campaigns without adding hours to your pre-session workload.
It’s what I do to level up my games. And it works perfectly whether you run homebrew campaigns, published adventures, or long-running sandboxes.
Cheers,
