Let's start off with a very basic question - What is an Imperial diplomatic office outside the Imperial space called? Embassy? Consulate? Legation? Something else?
Consulate: The residence or official premises of a consul.
Consul: An official appointed by a government to reside in a foreign country and represent his or her government's commercial interests and assist its citizens there.
Embassy:
1. A building containing the offices of an ambassador and staff.
2. The position, function, or assignment of an ambassador.
3. A mission to a foreign government headed by an ambassador.
4. A staff of diplomatic representatives headed by an ambassador.
Ambassador:
1. A diplomatic official of the highest rank appointed and accredited as representative in residence by one government or sovereign to another, usually for a specific length of time.
2. A diplomatic official heading his or her country's permanent mission to certain international organizations, such as the United Nations.
3. An authorized messenger or representative.
I'm thinking the distinction here is Embassies are for places you have higher level gov't relations with and Consuls for those places you need a presence because you have some ex-pats or travellers there, but where you maintain few higher level governmental ties. So Client States would get Embassies. Independent States might well get Consuls, or Embassies, depending on the situation.
Legation:
1. A diplomatic mission in a foreign country ranking below an embassy.
2. The diplomatic minister and staff of such a mission.
3. The premises occupied by such a mission.
Legate:
\Leg"ate\ (l[e^]g"[asl]t), n. [OE. legat, L. legatus, fr. legare to send with a commission or charge, to depute, fr. lex, legis, law: cf. F. l['e]gat, It. legato. See Legal.] 1. An ambassador or envoy.
2. An ecclesiastic representing the pope and invested with the authority of the Holy See.
Note: Legates are of three kinds: ({a}) Legates a latere, now always cardinals. They are called ordinary or extraordinary legates, the former governing provinces, and the latter class being sent to foreign countries on extraordinary occasions. ({b}) Legati missi, who correspond to the ambassadors of temporal governments. ({c}) Legati nati, or legates by virtue of their office, as the archbishops of Salzburg and Prague.
3. (Rom. Hist.) (a) An official assistant given to a general or to the governor of a province. (b) Under the emperors, a governor sent to a province.
So, it seems to me the order of importance is:
Embassy
Legation
Consul
But I'm only sort of guessing as Legation and Consul both seem to be less than an Embassy, but perhaps they differ in character rather than rank.
