How would portals to a pocket space operate? For example, a Time And Relative Dimension In Space, whose interior is a technological, semisentient (occasionally fully sentient) organism used as a temporal and spacial vehicle who is connected to "reality" via a coral box; which, in an adult, uncloaked state, appears as a smooth, metallic cylinder (yet is infamous for the disguise of a crippled one: a Police Box from England in the decade of 1960 CE; despite another cripple having the less-infamous disguise of a diner from Utah, USA in the year 2015 CE).,(reply>), Haha I understand that reference! Doctor disco out!
