I've been playing some Vampire: the Masquerade, and it's struck me that there seems to be a paucity of online tools to aid Storytellers. To make things easier for myself and for anyone else who might find it helpful, I've employed Spwack's html table tool to make some easy random generators.
First, a PC generator. It includes all the Camarilla and Sabat clans from the core rulebook, with page references. I did not exercise any influence on the distribution of points, except that I made it impossible to spread out abilities beyond what I can imagine players wanting to do. Merits and Flaws are included in their own separate generator, and always balance each other out, which you can tweak as desired.
Next, the immortal relationship generator, to characterize the centuries-long personal history of vampires and other undying beings. To establish a relationship, designate two characters and hit the generate button. If they've been around for only a few decades, use "modern nights" to establish the two main events in their relationship and how they feel about it. For characters of an age typical of older vampires, include later entries. For example, the relationship between two 8th generation vampires would include the 8th, 9th, and all later generations through modern nights. If they are wise, they consider the entirety of their history in deciding how to feel about each other. Otherwise, they use knowledge picked up in ancient times but are only motivated by events of modern nights.
To aid in brainstorming, a vampire scheme generator. Decide whose scheme it is and who their target is, then hit the generate button to get the broad strokes of a plan to deploy against their victim.
This last one is probably only useful to me. It's a random encounter table for when the vampires of my chronicle go wandering the streets of Chicago.
