Seems you know some Chaos fluff I wasn't aware of, and I dont have any plans to become some powerful slaanesh sorcerer. And who knows maybe slaanesh do like me, a little playthingie. But ill give it some thought, maybe others have some input on the matter.
Haven't done much thought on Grand Sire part yet.
When it comes to Neferata, my initial thinking, was that my character has been kept in the dark about Lahmian society, but guess that having an opinion on the matter, can make for some interesting debates(to but it mildly).
Just dont feel like being decapitated by Lesa on sight. Another thing to think about.
But was just waiting for some response to my character, do have a few holes in my story that can be developed into side plots and/or history. The slaaneshi cult did say they work for a 3rd party. Did they lie or speak the truth. Lie means that Slaanesh have plans for Lahmian vampires, and working on a way to corrupt there bloodline. Truth, who is working on a curse that can disfigure a Lahmian Vampire, both Lesa and Neferata springs to mind (maybe a bit obvious) for a way to get revenge on the other party. But maybe just a lesser vampire, that want to earn favour with either of the 2 powerful vampires, or maybe a powerful vampire that just want all Lahmian vampires to suffer.
But ill consider youre offer Mr. Nightwere, it does give some history to my character, that can be developed upon.
