I've been reading through the SCE/Corps of Engineers novellas and just finished "Failsafe" by David Mack. It stuck me that since "Wildfire" there has been a reference to the Galvan VI incident in every story. Now, I understand that for all of the characters it was a traumatic and for some life-changing event so it's understandable that there are ongoing repercussions for many stores afterwards. But that got me wondering about the timeframe for the Corps of Engineers. Is there any indications of when the stories take place relative to each other and relative to the rest of treklit? Also, are there other non-Corps of Engineers stores in which Corps of Engineers characters appear? I am aware of Nancy Conlon's role in the Voyager relaunch and Sonya Gomez's cameo in the fall, but is there anything else?
