From the introduction: Castle Courtyard The walls of this cozy green castle courtyard conceal many secrets and conspiracies.

The easiest way to use it is to play it on a TV laid flat on top of a low table - 40” TV would be the perfect fit for the gridded versions of my maps (but there's always gridless versions for other TV sizes). You can also use a projector or VTT like Roll20.
