Parego Regicona Edit
The Parego Regicona is the local name for the large island in the centre of the city formed by two branches of the River Adivian, namely the Westchannel and the Southrun. The island is divided by a number of canals and surrounded by an encircling wall with chained arches spanning the entrances to the internal canals. In times of war and civil disobedience chains can be hoisted between the arches to prevent access to the Regicona. Lifting bridges cross the canals at regular intervals which can be hoisted aloft to allow the passage of water craft through the city. The nobility of Westcrown have their manors on this island.

- Rego Aerum
- Rego Aerum, or "Treasure Sector" is made up of the Siar, Ghiam, and Karhal islands. The Southernmost island was made an exclusive city park (due largely to the mysterious inability to complete any buildings attempted there -- a long and strange history of accidents in the area) in 4040 AR.

The illicit Dusk Market can be found in Cader, though it rarely sets up in the same place twice.

Parego Spera Edit
Parego Spera is the still prosperous section of city were trade trumps politics. The longest canal in the city can be found in Spera as well as the two great Pegasi Bridges which date back to the days of Aroden. The three sub-sectors that make up Spera are Scripa, Pena and Sacero. The canal, or Canaroden, is a much-visited spot by tourists because of a quite unique feature: running along the northern wall carved impressions of the twelve guises that Aroden used to walk Golarion: beggar, thief, fisherman, hunter, shepherd, farmer, soldier, merchant, tailor, craftsman, artist, and scholar. Although there has been much defacing of the images of Aroden over the last hundred years, the damage has mysteriously disappeared.
