I see a lot of talk on the vampirism thread about vamping this or that person and causing tons of damage to them, and things like that. Though being able to utilize every aspect of that tool is important (what’s the point of knowing how to swing a hammer if you refuse to use the claw part to remove bent nails?), hurting others is a very small, select part of what vampirism can do.
Before I dive into that, imagine you’re a tiger that follows a herd of wildebeest. You get hungry, you catch a wildebeest, and dine like a king for a day or two. You continue to follow that herd, and only harvest when you need food. You typically harvest the easiest prey to make your hunts easier, so you go after the sickly, the old, the infirm, while leaving the healthy ones be. The herd, in turn, benefits from this because they will only move as fast as their slowest member, and a wildebeest with a broken leg doesn’t move too fast (which, incidentally, might starve the herd, since they’re eating up all the grass in the area and refuse to move on). In short, the herd benefits from the tiger’s predation through the removal of the weakest individuals, and the tiger has a vested interest in maintaining the cohesion of the herd.
Now, back in civilization, Thomas the vampire is scoping out possible targets for feeding at his local club/coffee house/bar/where ever humans are gathering this week. He’s noticed, like most vampires, that chi with a heavy emotional charge tastes the best. In most people, this tends to be anxiety, depression and sexually charged energy. Thomas finds his mark in a girl sitting with a friend crying into her cup of what ever.
He walks over and introduces himself and starts feeding off the anxiety/depression (its amazing how linked those two are). Because Miss Megan (or whoever) immediately felt a twitch better after shaking Thomas’ hand thanks to a quick snack of that negativity, she opens up to him and dumps all of her problems on him, while he enjoys a delightful full course meal. Through tears, once she’s just about spent, she says, “I can’t believe I opened up that much to you. Thank you for listening, I feel tons better!” and Thomas, completely juiced up, simply says with a smile, "That’s what I’m here for!"
Fast forward for a few weeks doing this, and an entire subculture of people are ready, open and willing to dump all kinds of emotionally charged energy on Thomas, who isn’t complaining in the slightest that his nightly “hunts” almost always end with his prey coming to him.
In the above true story (names were changed), Thomas almost took stewardship over the crowd, in much the same way the tiger took stewardship over the herd of wildebeest. He harvested the chi that the herd (or people, if you prefer) most wanted to be rid of, but had no idea how, and both were made better for the exchange.
