I'm going to add a rank to Her Imperial Majesty's Military that translates into Marshal, which will be equivalent to NATO's OF-10 pay grade and only able to be held by the Empress. Would the Skaran Latin translation be Imperator Skarani or Imperator Skaranum (nom.)? I'm fairly sure it wouldn't be ablative, accusative, dative, or vocative.
