We are about to start 3 linked campaigns that will all use ISDs. The three groups will then merge after the Dilgar War, Earth Minbari War, and War of Retribution Campaigns to loosely follow the chronology of the show after the Fall of the Narn. It is possible that the Narn do not fall.
We will then be using ISDs throughout that larger campaign with each turn being something like 3 months. I am running this event and playing in at least 1 if not 2 of the mini campaigns before we come back together as one group. I am then going to step back and moderate the campaign during the Shadow War period using a combo of Technomage ships, Raiders, Ancients and maybe the Soul Hunters ship as a kind of stuff happens fleet.
Once we get done with the Shadow War, providing that the Army of Light wins, I will then get to break out my Drakh. If they don't win, I am not sure what will happen. I am still curious why the Drakh are entirely excluded before 2261, if you read the novels it seems apparent that they are at least somewhat active at that time. Even the RPG book on the Drakh makes it seem like they were just held on the bench, not entirely out of the picture.
