The 27th Cartographic Congress Vote Runoff (Patreon)

Three maps have made it to the runoff this month. In descending order of old-school-ness: 

Senator Roose proposes a funhouse dungeon deathtrap, like from the old days of D&D. (1980s, 1st ed.)

Senator Raffaele proposes a mind flayer dreadnought spelljammer. (Late 1980s, Spelljammer)

Senator Fraz-Urb'luu proposes a great estate on the plane of shadow, with surreal, twisted architecture, doors that lead you back where you came from and lots of gargoyles. (Mid-1990s, Planescape)
