Camp 19

Camp 19 is one of three concentration camps located in the Barren Ridge of the Eastern Crescent, part of the Northern Regions.

Triangular Arrangement
According to Crimson Earth: Sodom and Gomorrah, Camp 19 is situated with Gomorrah, the camp mentioned in the chapter. Interestingly, Sodom is also the sister camp of Gomorrah, suggesting the three are connected in a triangular arrangement.

Wallryder's statement on the three camps
Wallryder staff and the primary author told viewers and readers on Twitter in December of 2014 that the three camps were arranged in a triangular pattern, and that Web and Nord were probably killed in between Gomorrah and Camp 19.

Role
Camp 19 is a killing field, mentioned in Crimson Earth: Hourglass:

"The man quickened his pace. He had to put more distance between himself and the killing fields. The blood-soaked grounds were nary six miles back, but it was not the Relievers he feared."

Location
West of Gomorrah.
