Ohhhh, wow. I just read through the whole read (which thinking back upon it really wasn't all that needed...) but uh. *coughs* Anyways, this looks really awesome.

I can't WAIT to play it in Oblivion! I actually do like the name Arch-Patriarch (though I think maybe a - is needed?) but what exactly are these familiars? What power do they hold over the vampires? I was curious about that.
Another thing would be that I'm not a big fan of the red... bib around the stealth armor.

I mean... to me it really does look like a bib, and takes away from the awesomeness of the rest of the armor. So I was wondering if you'd consider making that separate from the armor? Like something else you can add for effect? Because it really... eh for some reason. xD
I love the shrine for the original vampire- very sweet, very spooky. Overall, this is looking like one of the best mods I've seen so far. Honestly, I'm okay without vampire hunters. Mostly I just want something to DO with being a vampire, rather than just looking like your character aged about 50 years. (I mean, you don't even get FANGS in Oblivion! Uncool, man)
Oh, that's one more thing! Would you consider making players able to wear fangs. >w>
