The name of a city as well as a district in the Seattle metroplex, UCAS, to the south of Down Town.
The Reality Hackers are based in Puyallup city itself.
The Knights Of Tarislar are based here in Tarislar, near the river. JC, Pathfinder, and Gard live in a tower block in their territory.
A lot of the district is taken up by the Barrens, and doesn't have a Matrix connection at all. All in all, not a bad place for Shadowrunners to live in.
