It was during a lecture they probably should have been listening to that Sara Thompson doodled the Dungeons & Dragons Combat Wheelchair on the back of a textbook. They'd been talking about it for a while, the wheelchair, irked by a game that offered players limitless freedom to be whoever they wanted but still struggled to fully represent them. So they did something about it.
A few years later, that Combat Wheelchair add-on for Dungeons & Dragons is on a third edition, spans dozens of pages, and has reached right around the world. It got the attention of writers working for D&D maker Wizards of the Coast, inspired bespoke miniature models and was featured by mega-popular Critical Role host Matt Mercer.
