The Great Bibliopolis

The Great Bibliopolis* is an episodic, rotating GM, genre-bending, system-bending campaign, similar to a West Marches, or an adventure anthology like *Candlekeep Mysteries*. The players are also all GMs, and they take turns running short adventures for each other. But rather than unconnected one-shots, the same pool of PCs are present, so that characters can arc, relationships can develop, levels can increase, even overarching stories can happen.   It's set in a vast, labyrinthine, plane-warping library complex, full of mages and scholars and bizarre and magical tomes. The PCs are those scholars, or library staff, or hired hands, or just stumbled in off the street. The adventures begin and end in the library, and could involve the party getting pulled into a story book, an extradimensional space, some forgotten tower, or whatever the GM can contrive. If that means you want to run a different game system (from the base 5e), in a different setting and genre, do it! It's kind of *Star Trek*'s planet-of-the-week meets *The Pagemaster*.   Having a central hub means we can have a character pool, and take different 'away teams' of characters into an adventure depending on which players are available. We could also theoretically each create multiple characters, and pick and choose which one we want to play each time. This 'away team' model also means we can have a larger player count, and then form different parties with those whose calendars line up for a game session.   To take part you should be willing to run games at least occasionally, even if not on a regular rotation.   We use D&D Beyond for character management, with content sharing enabled from most source books. So far we've used Roll20 for running games, but it's up to each GM what VTT they prefer to use while hosting a game.
