Similarly with several other titles from season 2 (and a possible connecting element between them), a possible source for "Jubilex" is the site "pathfinderwiki" website and similar gaming sites; the use of a Warhammer gaming card early in the season hints at this.
The very final shot ends with an aerial/satellite view of the El Paso(USA)/Ciudad Juárez(MEX) border, with its curve (Rio Grande/wall) closely matching the same of the real, & once disputed, border around the Chamizal area, although the shown landscape much differs from the reality. (Chamizal is mentioned in an earlier episode as the scene of a shooting).
Given Chamizal's history (once a lawless, juridistictionally ambiguous zone, but now parks, monuments, colleges & sports facilities) & the "bridge" theme, this is likely an image the creators deliberately used.
