Helena von Culper
Helena was appointed by the new Chamberlain of the Seal, Baron Amadeus Mencken in order to clear the house of the pawns of his predecessor. Helena, as Master of the Komission of the Imperial Archives is head of one of the vital information gathering organisations of the Empire. This information she also passes to other members of the Lahmian Sisterhood. 
She is unaffected by the touch of the sun, is able to cloak her true nature from those with magical senses and has no fear of holy objects.
