Was perusing the Eidolon City in the Sky (GCP-SW-1007) mapping out entities and noticed that I can't ever seem to find Burning Rock. Doesn't show up on any of the maps I can see, but there are references to it. The Timeline (pg36) for year 4705 names it, as well as 'Old City' (pg 126), and Adventures (pg 157). Lastly it shows up on the Food & Lodging price chart (206). Almost seems akin to a Sel-Kai district.
Searched the forums here, but apologies in advance if I've just over looked it!
