Okay just so everyone remebers, when discussing Dalila, she's only known as the Magister outside the Vitores Tenebras. All the Imperium knows about "him" is that "he's" been assassinated by the Officio Assassinorum at least five times yet each time has re-appeared completely unscathed. They also know the Magister is a psyker of some kind (courtesy of a certain Greyon Autaris).
