I know this fight is basically Chaos against the Vamps, but can I backstab the vamps later on for Nagash? It would only be a small sideplot which would come into full action near the end, and I would really like to be some insane, vampiric disciple. Maybe even the last one! Or is Nagash going to be truly gone at the end of this? That would be a shame, he should be nearly completely destroyed, but, in the Warhammer world, all awesome bad guys are never quite vanquished, and I don't think that he should be an exception.
Of course, I have another idea for a vampiric snotling that likes to go round causing trouble (e.g. turning Wurrzag vampiric,terrorizing random farmers) but I would like to have a dark character too. I don't mind much if Nagash is destroyed, but I did have a small plan involving him.
My character would start off as an insane necrarch who captures and tortures souls and studies them; he channels their power into his spells using monstrous devices. But near the end the vampires start to doubt his intentions, he seems extremely evil and isn't afraid to use the vampires' sould either. He then could do a massive ritual in a big battle to summon Nagash, but I haven't thought too much about what happens next. This may sound a bit stupid, but I hope this character's good enough.
