Morvenn Vahl
Morvenn Vahl is a living example of both a great warrior of the Emprah as well as someone who gives no shits about political maneuvering. As the Abbess Sanctorum of the Sisters of Battle and a member of the Order of the Argent Shroud, she was chosen for the position as the High Lords wanted to manipulate someone young. Given what her order is known for, it shouldn't have been a surprise what she would have done after accepting and being inagurated. She's known for leading from the front, preferring to have her second-in-commands handle her duties on the Senatorum Imperialis, and managing to make the derptastic Paragon Warsuit look at least somewhat decent.
