A
region commander of the
Empire (in the
Star Wars universe). A
Moff might
command a couple of
star systems,
technically referred to as a
region. There were
Moffs long before there were
Grand Moffs,
reporting directly to the
Emperor(control freak as he was), but after
Moff Tarkin suggested that a
higher level of
control be asserted to handle the problem of
raiders,
rebels,
pirates and
smugglers escaping into another
Moffs region when hunted, he was
rewarded by being
appointed the first
Grand Moff.
