Wizards of the Coast? Oh, interesting. They’re the ones who published Magic the Gathering, and they bought out the company that made Dungeons and Dragons and are now the modern publisher of it. Not to mention, of course, they published Pokemon cards during its earliest days. Although I remember them having some of their own retail stores, nowadays they no longer have any retail stores, they are wholly a publisher/supplier.
Plus, they’re a company that got their heyday in Washington state.

And this is also interesting. Dungeons and Dragons created the Open Game License for their gameplay system, allowing third parties to create different game content that used the same gameplay mechanism. Later on, it panned out and wasn’t quite so popular, partly due to misunderstandings on both party sides.
