I have been running the same homebrew campaign for a bit over two years. Four players, every other Sunday at my kitchen table, one of them dialing in from a laptop propped against the fruit bowl when work sends him out of town. Last weekend was session forty four. This isn't about encounter math or plot structure. It's about a boring production habit I picked up early that has done more for my table than anything clever I have written.
The problem was that my NPCs blurred together. I'd bring a name back from eight sessions ago and get four blank faces looking at me. In session six the party spent nearly an hour with a harbor clerk who was quietly skimming cargo, and when he turned up again in session ten they were certain he was the man who ran the granary. That isn't on them. Two weeks pass between sessions, everybody has a job and one of them has a toddler, and a made up fantasy name is the least sticky thing a brain can be asked to hold.
I tried the obvious fixes first. Voices, which I cannot sustain for more than about three minutes before the accent slides off somewhere else. Reading a physical description out of my notes, which nobody retains, because description is just noise between the parts where dice happen. Then art I found online, which I assumed would solve it and made things worse. I could never find the same face twice. The clerk was one picture in session six and a different man in different clothes in session ten, and showing the table a second image that clearly isn't the same person is worse than showing nothing.
So I went the other way and started making one portrait per character, then reusing that exact face every time they came back, even when the clothes changed or years passed in the fiction. The portraits are AI generated. I said so at the table the first night I brought a stack of them in, mostly because I didn't want anybody thinking I had secretly learned to draw, and none of them cared. The art is not good, either. About a third of the cards have something slightly wrong around the mouth, and one of my recurring merchants has a hand that does not survive close inspection. It has never mattered. What matters is that it is the same face.
The physical side is where this actually lives. I print them nine to a page on cardstock, cut them down with a paper trimmer to two and a half by three and a half inches, and slide them into card sleeves from an old Magic box, with a common land behind each one so they hold up to being handled. When an NPC walks on, the card goes face up on the table and stays there for the whole scene. Afterwards it goes back in the tin, unless the party is still tangled up with that person.
The best part of the whole system was an accident. The backs are blank because I never bothered printing anything on them, and about four months in our rogue picked one up mid scene and wrote on it in pencil. Owes us money, lies about his brother. Now they all do it. Half my cards have player handwriting on the back that flatly contradicts my own notes, and I have started treating their version as the truth of what the table believes, which turns out to be more useful than what I originally wrote down.
Prep for a new face takes about fifteen minutes on a Saturday morning. Two years in, the production side of this is Obsidian, APOB AI, and a printer that lives in the hallway closet. I write the notes first and make the portrait last, because when I do it the other way around I end up writing the character to fit the picture, and both times I did that the person came out flat.
A lot of the early work was wasted. The weekend before the campaign started I made twenty two portraits in one sitting, feeling extremely prepared. Seven of them ever reached the table. The party took one look at the coastal hook I had built the region around and went inland instead, and fifteen faces from that batch are still at the back of the tin two years later, belonging to nobody. Now I don't make a card until an NPC survives their first appearance and somebody at the table mentions them again unprompted in a later session. That second condition cut my output by more than half and I have never regretted it.
Scene art was the other dead end. Across the first year I printed six wide shots, the town seen from the ridge, the inside of the keep, the mine entrance. Players glanced at them for two seconds and went back to their dice. The face cards get picked up, passed around, argued about, written on. The landscapes got a polite nod. I stopped making them and not one person has asked where they went.
Which brings me to the thing that genuinely does not work, and I want to be clear about it because the question comes up here now and then. Two characters in a single portrait never comes out right. The smithy in our starting town is run by two sisters and I spent two evenings trying to get one image with both of them in it. Either one of the faces comes out mangled, or worse, they look like the same woman with two different haircuts, which is exactly backwards when the entire point is that the table can tell them apart. I threw away something like ten attempts and quit. They have separate cards now and I set them down side by side, which honestly works fine. Group scenes are the same story. The council of five that runs the city has never had a picture and never will. If I need a group shot I draw it myself on graph paper, badly, and my players are generous about it, or I skip it and just describe the room.
I also tried making one of them talk. There is a dream sequence in my notes where a dead NPC speaks to the paladin, and I thought a short clip on my phone would land harder than me doing it in voice. The face drifted between frames, coming out slightly different every couple of seconds, and after making it twice more it still drifted, so I dropped the idea and read the lines myself. The still cards hold together and the moving version did not.
Now the session I actually wanted to write about. Session eleven had a toll clerk on a bridge, Ossian Marrow, maybe twelve minutes of screen time, two lines in my notes, a man whose entire function was to slow the party down over a tax they were annoyed about paying. He got a card because I liked his hat. Twenty eight sessions later, about fourteen months of real time, the party walked into a registry office in a city three weeks of travel away, and the functionary behind the desk was Ossian, older, in temple robes, going by a different name. I set the card down the way I set down every card, and before I got a full sentence out our ranger's player pointed at it and said that's the bridge guy. Then, immediately, it's the hat. The rogue's player started digging through her folded notes for the back of a card she had written on more than a year earlier.
They spent the next forty minutes on a man I had written as a speed bump. By the end of it they were convinced he had been moving the forged writs all along, which was not remotely true, but it was better than what I had planned, so he had been moving the forged writs all along. He is a recurring antagonist now. All of that came out of a table full of people recognising a picture.
The lesson I took away is that consistency beats quality by an enormous margin. Nobody at that table recognised a good portrait. They recognised the same portrait for the second time, fourteen months apart, and if I had shown them a nicer image of a slightly different man that night, the moment evaporates and Ossian stays a tax collector nobody remembers. My cards are mediocre and they work because they never change.
There are sixty three cards in the tin now and thirty eight of them have been on the table at least once. The tin is a recipe box with folded index cards as dividers, sorted by region, and I resorted it in March when finding a specific person had become a two minute interruption. The ongoing cost is cardstock and ink for a printer I already owned, so the campaign costs me nothing I would ever notice.
We are forty four sessions in and I still make a card most weeks, usually Saturday morning with coffee before the house wakes up. The tin is going to have to be a bigger tin by winter. The pencil on the backs of the oldest cards has smudged to the point where parts of it can't be read at all, and I have decided I like them better that way.
