| +1 trade routes max on city|
+50% on city trade routes
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.
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.
