A city improvement exclusive to the Forgotten obtained from the Commercial Espionage technology. Surreptitious Research increases the number of trade routes on a city by 1, and increases the Dust produced by that city's trade routes by 50%. This construction replaces the Scientific Envoy city improvement available to every other faction.
Lore[]
By stealthily listening in on conversations, gaining access to draft versions of contracts, and otherwise tipping the odds in their favor, Forgotten Trade Routes do miraculously well.
