In 2004, Sgt. Bates made the first trade agreements over food with the people. With not-so-open arms, they admitted almost all of the Athosians and Atlantis expedition members to their world when Atlantis and it's mainland were threatened by a massive hurricane only to sell them out to the Genii, informing Cowen that Atlantis had been evacuated and helping Commander Acastus Kolya find a way to get past the city's defenses with his raiding party.
