Ok, so this is nowhere as impressive as these fantastic maps and terrain... but it might amuse.
I'm currently running the Dungeons of Drakkenheim campaign (I highly recommend it!). I was struggling to introduce one of the factions (the Silver Order) to the party, so I decided that they would have a "random" encounter with one of their knights in the ruins - the knight is surrounded, the PCs help, now they can talk kinda deal.
I decided to base this NPC on a paladin a friend played in another game, named Antoine Lavache - brave, honest, generous, but also overbearing and supremely confident. But that evening I did not have the time I expected to prep due to real life getting in the way. Because some of my players are remote, we use roll20 for our battle maps. So I just recycled another street map from a previous session in Drakkenheim (a play test, technically not the same campaign). It worked fine, but it was full of the old tokens, so I had to "token-prep" the map in a hurry (ie, "live" during the session) - removing all the old tokens and adding new ones.
One of my player is a bit of a goofball, and rarely ever takes a "serious" token. And I realized that his old silly token would just the thing for this powerful, arrogant knight...
