There is a program (mainly maintained by alchemists) that picks people from the general human population.

The way they collect these curious potential donors is likely an obscure website that you can find if you dig far enough in the 'vampire' section of a google search.

These donors are often the kind of people that believe vampires really do exist and want to help (if you catch my drift), but there's also been people that were formerly homeless and had nowhere to go. Maybe even a combination of the two. One of Christian's favorite feeders at St. Vladimir's Academy was actually an elderly woman named Alice (lord what I'd give to know how she got into that).

No matter what your circumstance or reasoning was, the alchemists would make arrangements for you to go through the screening process to evaluate your health, and eventually you'd be sent to one of many compounds around the world to begin your service as a feeder.

To start with, the website states you must be in acceptable health before they will consider your application. This is to control the quality of the blood, and unhealthy blood wouldn't taste as good as blood from a healthy person would.

Once you've submitted an application to the alchemists, they contact you and send you to a clinic (owned by the alchemists, of course) where they pay for you to go through a general checkup to have a number of tests done, mostly to check for blood-related diseases such as anemia, or thyroid issues.

After the initial checkup, the healthiest of the new feeders are contacted by the alchemists. Transportation is arranged by the alchemists, and as soon as the feeder(s) in question arrive(s), they are given a comfortable room to live in, and are put on the rotation schedule for the moroi.

For the others that still need work but are still overall healthy, they are given a room just as the other feeders but don't join the rotation until they are ready and up to 'acceptable' standards.

Each feeder gives blood twice a day, every other day, to ensure they aren't tired out. They are given as much as they want to drink, are given three meals a day plus snacks, and everybody is given a monthly allowance (similar to social security) on a special card to buy clothes, toiletries, or whatever they desire.

The blood given to the moroi is already very valuable, so the feeders do not have to pay for rent or utilities.

There has to be a catch, though...

Correct. There is a catch. Moroi saliva has strong endorphins, and it's easy to become addicted to their bite.

Most of the feeders that come through don't really ever want to leave, and why would they?

They have a roof over their heads, they're safe, they don't have to buy any groceries or pay any bills, they essentially live in the lap of luxury and the only price to pay is a little bit of blood every couple days or so - and the bites just might be better than sex.

Leaving. It's a funny thing.

The feeders are free to leave when and if they ever decide they no longer want to be a feeder. The whole point of being a willing human donor is the consent. Once you rescind that consent, it's time to go. Simple as that.

When the feeders first arrive, a financial account is set up for them. It links directly to a bank account managed by the royal treasury, and the aforementioned card acts as both an identification card and a debit card. As long as they are a feeder, they have access to the funds put on that account. Those funds cannot be transferred to an external bank account.

When they decide they no longer want to be a feeder, they are discharged. They lose their card (and the funds on it), and a trained moroi will compel them to forget their life as a feeder before sending them on their way. This discharge takes a year to complete, first to wean them off the bite addictions, then to rehabilitate them so they can be released back into the general human population and live independently again. Typically they'll be set up with a small apartment and enough money for a couple month's rent, plus extra for food, utilities, and other basic needs while they look for a job.

Feeders that have decided to leave the program are given a small tattoo that's similar to that of an alchemist's lily tattoo. This tattoo is received in the latter six months of the one-year service lament. Except, in this case, the tattoo is a small, freckle-colored spot located inconspicuously on the body. The ink used is enhanced with moroi earth magic - known for its strength in compulsive charms. While it wouldn't last forever, the compulsion would add another layer of security around the memory modification they receive upon departure and ensures they don't talk about their experience as a feeder to other humans while in 'rehabilitation'.
