New Setting Concept!

So I have a ttrpg setting I've been working on for a while now, here's the intro just a teaser.

Picture, if you will, an endless expanse with rolling fields of jade green grass. A heavy brume, like smoke in water, obscures the view of anything more than 100 meters from the end of ones nose. Dozens of winding paths twist, turn, and fork in every direction, no one path having any particular destination. Amidst the fields, pathways and mists sits a solitary mountain with a heavy wooden door, seemingly milled from one solid towering piece. Carved in it’s center is an inscription: “What in hells did you travel here for?” Beyond the door, residing inside, are countless caravans, houses, shops, restaurants and courtyards cascading in an endless downward spiral. Never residing in one place and yet never moving at all. Peoples of all shapes, sizes and colors, bustle about their lives. Regarding each other as both comrade and competition. At it’s lowest point, buried deep in the mountain, sits Ganymede. Atop his simple stool, a bottle in one hand, a dagger in the other. Beware all adventurers who enter, here, your purpose is Ganymede’s sport.
