The World of Cittàgazze was one of many parallel universes. Cittàgazze and Sant'Elia were two of the towns in this world.[1]

The world appeared to be quite modern; electric lights and fridges were used.[1]

Spectres were common in this world for several generations, however their number was greatly multiplied after Lord Asriel created a huge window through his world into that of Cittàgazze.[1]
