Okay so Blight you already know pretty well: a psychopathic Culexus Assassin assigned to the Tenebarite Cabal via authorization of Lord Inquisitor Greyon Autaris. Placed under the command of Lord Inquisitor Alexei de'Ossmann since he's more or less okay with having a Pariah around.

To put it simply, Blight doesn't play well with others. In his mind everything falls into two categories: people he can kill, and people that give him permission to kill. The former he likes to torment as much as possible and the later he often get's frustrated with, mostly because they don't let him kills things enough. Everyone he meets usually finds him highly disturbing, and not just because he's a soulless void in a human body, but also because he's a maniac with the same destructive potential as a miniature Exterminatus.

Dalila Isminger: Former Lady Inquisitor of the Ordo Hereticus and powerful Telepath who faked her own death and then joined the Vitores Tenebras, becoming leader of it's Animus Branch under the guise of the mysterious Imperator.

Dalila is a very calm and collected sort of person, and hardly seems like a megalomaniac that plots to destroy the entire Imperium. While she seems nice enough, to her pretty much everything is a means to an end, and once it's outlived its usefulness it is deposed of, usually on her orders. She's deceitful, manipulative, and utterly ruthless, so yeah pretty much the "evil mastermind" type. Also, Dalila doesn't get along very well with her colleague Edrith Cambion, as she seems his experiments with the powers of the Warp as a catastrophe waiting to happen.

I hope all that description helps in some way.
