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 birthstones associated with each month, and people wear theirs for miscellaneous minor helpfulnesses, like nullifying influenza, and also you can put other kinds in arrays to create resonances for more serious healing. - I said 'you' but really I mean licensed professionals; it's complicated business. Oh, and sometimes they use different types of herbs as part of those, too."

Homeopathy

Exists, is magic.

Natural Order

 The universe has opinions about the natural order. The first few times something unnatural happens, it is much more difficult than it should be, but then the universe gets used to it and stops objecting. For example, the first few times someone tried to make vacuum, the containers crumpled even though they were as strong as containers that worked for that later
