In order to fully understand this observation you'd have to have played w101 an p101 up to Marleybone in both games. Alright so I'm checking out the map in the Marleybone sky way an notice a city doodle at the top of the map. It isn't a place you can go to but could it be where all the wizards are? In w101 the spiral door you enter from isn't the front gate but the church in regents square. On the other side of that gate where the two red guards are could be the skyway where pirates sail. Also I recall Rat Beard having a dialogue that mentions "dancing on rooftops" instead of fighting in the sewers. So wizards an pirates may not just be in the same spiral but also in the same time period. Cool thought eh?
