Stars, magic, and other bullshit

Stars

Stars are dead people. They influence things in magic ways. If you get high on a specific drug (omnilol), you can talk to them.

At first, each dead person is on their own, but eventually they merge together, frequently with others of their birthday at first. This usually happens pretty quickly: it is really easy to fuse accidentally, and gets moreso over time. Eventually, most people's clouds get merged into the One cloud.

Influenza

Influenza is an illness that occurs at predetermined times depending on the stars, in different ways for every birthday.

Crystals

There are birthstone crystals associated with each month, which can be worn by people born in that month for minor benefits like nullifying influenza. Crystals can also be placed in complicated arrays, often with herbs, to do more serious things, like healing and power generation. (The power grid runs off of crystal arrays.) Placing crystals in array-like arrangements accidentally is very dangerous, and people who are not trained professionals should generally not touch crystals at all.

Homeopathy

Exists, is magic.
