The whiteboard became the thing.

Version 1 was printed cards in plastic sleeves. Version 2 added a printed map. Somewhere around the fourth iteration, we taped a whiteboard section next to the map and started writing active quests in marker.
The whiteboard changed everything.
It felt alive in a way the printed cards didn't. When a quest updated, we erased and rewrote it. When something happened mid-campaign, a surprise, a breakthrough, a wrong turn, we wrote it on the board. The kids started adding their own notes.
Most of the system now is the whiteboard. The printed elements are context. The whiteboard is the actual campaign.
