In the world of Stormlight, we have the Weeping season, where there are no large storms [highstorms], we don't have any new Stormlight. How did the Knights Radiant deal in the past? Like, how did they handle this time?
Well, there's a couple of things, some are spoilery for the books. Large gemstones can keep the Stormlight, though. Some dealt without and just didn't have it. In some cases, they had the large gemstone reservoirs. It was a thing they planned for and there were a couple of other little hacks that are not obvious in the beginning of the series. So, you actually get a RAFO on that.
