Overview
Orders issued at Kar Duniash concern wars separated by distances no officer can supervise directly. Battlefleet Ultima’s headquarters must assemble a usable picture from messages arriving at different times, then send ships to act on it. The vessels may be committed long before anyone learns what changed after the last report.
Its dockyards and communications stations give the largest segmentum a centre for that work. Beyond the Great Rift, maintaining contact has become a task in itself. A signal from Kar Duniash can tell an isolated commander that a higher authority still exists without giving him any assurance it has the means to reach him.
