Not many at the moment I know, but I will add more when I have time
to look at some,
and decide whether they are worth adding.
If you have a Ventrue page, feel free to mail me the URL, and I will check it out, and may even add it here ;>
The Ventrue section of the 'Kindred, The Embraced' home page
A nice 'History of Ventrue' page
have a look, it'll make you laugh if nothing else ;>
