Just a little basic stuff. Initially, this worldbuild was inspired by Ilona Andrews’ Kate Daniels series and was meant to be post-apocalyptic fantasy. Then it started to morph as I got into it. Some elements remained, others changed drastically. (Current word count: 26,365 including table of contents)
Magic ebbed throughout Earth for millennia. That is, until two generations ago when the birth rates for non-humans and mundane-born magicians increased dramatically. Despite this increase, the paranormal community remains in hiding from mundanes as it has done for 4000 years.
Paranormal governments vary by region with laws being set by the local government. There is no government as such beyond the local or regional level. Most localities set up laws regarding the basic necessities that allow society to exist (murder, theft) as well as concealment rules (which are mostly unnecessary due to the Shroud). Any region that has a government has a police force of some sort as well as courts. Everything else, including gender views, varies by region and faction.

The Shroud is only known to occur on Earth, near concentrations of magic and paranormals. Basically, it conceals the presence of magic and paranormals from mundanes. It also interferes with post-19th century technology. The Shroud is believed to be the result of a reaction between magic and some natural field present on Earth. Some, however, think that Demons generate the Shroud. The field does have some interesting effects, for instance mundane parents of a magician are unaffected by the Shroud for some reason.
Preferred fashion varies widely across the paranormal community. Mundane styles are popular throughout most of the Earth population. There are still some who favor robes or medieval/Ren faire inspired fashion, though. The latter group are more prevalent on the Realm, near the Keep, but are not uncommon on Earth. Style also depends to some degree on species and faction, for example the Satyrs and Nymphs lack nudity taboos, so often wear nothing at all.
