I was thinking, since, naturally, Inquisitors never go anywhere just by themselves. I was wondering what kind of throw-away peons to be following her around that she's going to get separated from, which would be better?:

1) Tempestus Scions (The Inquisitors best friend)
2) Mordian Stormtroopers (Since she primarily works in the Mordian sector)
3) Sisters of Battle (Since they are the warriors of her Ordo. Because the Deathwatch are the warriors of the Ordo Xenos, Grey Knights are the warriors of the Ordo Malleus and Sisters are the warriors of the Ordo Hereticus)
