This map is designed for use in my home DnD game. The central platform is 30ft high with 8 quarter circle platforms that expand (see 2nd version). The circular plates are intended to have Turret emplacements on them as tokens on Roll20, so they are blank on purpose. These turrets use the 5e Catapault spell to shoot cargo through tubes umder my main city. They expand over the glowing green pipes on the outside.
