Second Age Pavis has only been detailed in a couple of books by Ian Thompson ('Shadows of Pavis' and 'Masks of Pavis'), neither of which are considered canonical, neither of which were used for 'Pavis Rises' and neither of which had a map. So, the city's never been mapped during this age although there are some terrific 3rd Age maps covering the Big Rubble, which - spoiler alert - the Second Age city becomes, in time.
