The trailer for Warlords shows the agent (player) going into a building and seeing an ECHO of Keener, who in turn causes an explosion to occur. That may be the trading post, or the BoO, but regardless it is stated that Keener attacked the BoO with either said explosion or the biological weapon seen entering the vents later on in said trailer.
