Bornego was a country located somewhere on the planet located in the Sol system known as Earth. This country was known for its unique jungle sites, with lots of wildlife, a number of animals, trees and chasms.
This jungle was protected by a game warden, who once informed Green Arrow of an incident involving a couple of animal photographers getting attacked by giant ants. This turned out to be not entirely accurate, because the ants were not giants, but rather the people were shrunk.
