Academy Admiralty: Naming their highest ranks

Oof.  I'm kinda between preceptor militant and instructor of the fleets.  Lord of retribution sounds a bit too religious, even for a Vodyani defector.  Spear of Lysander sounds too egomaniacal.  Apostle of Justice has merit, but...I dunno.

Just think what shortened epithet he'd often hear in quick situations.

"Preceptor!"

or

"Instructor!"

Which of those would feel right?  On the one hand, "instructor" makes me think he'll turn around and go "no, you cannot have an extension on your thesis deadline."  On the other hand, preceptor triggers a little memory in my brain that goes "Cursory evaluation of Decepticon capabilities indicates a distinct tactical deficiency!"

I'm not sure which one makes me giggle more or groan less.

'Preceptor Militant' sounds like something out of Warhammer 40K, and 'Spear of Isyander' is too personal. Lordship is also kind of far from the academy's theme, and 'Instructor of the Fleets' should be the guy teaching space-combat at the academy, not roaming around fighting. Since the Academy is almost like Isyander's own church, I say Apostle of Justice works the best.

"Spear of Isyander" sounds too personalistic. "Preceptor Militant" sounds baroque and intriguing. So Preceptor Militant it is.

Spear of Isyander sounds like a flagship, whereas the Preceptor Militant sounds like a rank.

Thus I've casted my vote.

Spear of Isyander sounds fitting. 

Who the hell votes for Spear of Isyander, it sounds like a dick.

As Lysander say he seek "Justice" in cinematics, Apostle of justice seem the best.

"Instructor of the Fleets" makes most sense for the academy.

Preceptor Militant; while Spear of Isyander is cool, the Academy is less about him and more about the Lost.
