Imperators are the leaders of the High Legions, holding the second-highest rank in charr society (the highest being the Khan-Ur). The imperators are always descendants of the Khan-Ur, and only an imperator can claim such title. As there is currently no Khan-Ur, the imperators are the highest ranking charr and have the supreme authority within their legion's structure, acting as commanders-in-chief. As hinted by Seneca the Relentless, imperators are granted the right to personally interrogate, judge and sentence prisoners.
