Not to be confused with Izambri's thread of almost the same name (which is infinitely worse due to the lack of Oxford comma and lack of con-content. Con-tent. Content.)
Let's hear about some conworld holidays! Although I've written about a bunch of Lilitic holidays already, more is always better.
The resettlement of the inner belts was a major event in the history of postlapsarian Thet, and is commemorated each year by the residents of the modern city of Dis and its surrounding demes on nearby islands. In contrast to other anniversaries of events from the period, the Resettlement is a happy occasion and functions as the analogue to the new year in its cultural significance. (The actual start of the calendar year, some two months earlier, is a sombre time, as it is the anniversary of the Shattering itself.) Births, weddings, and agreements are thought to be lucky on this day, and it is a common date for breaking new ground on construction or the renovation of public works.
In more superstitious communities, this luck is said to be brought by a prophet or idol, most commonly Sarthía, Tetragnostica, or Myenga. Although Thessians are not known for their shrewd capitalism, some of these neighbourhoods have taken the notion of luck somewhat literally, and pool their money to purchase a large number of lottery tickets on this day. Symbols associated with the Resettlement include archaic construction tools—cranes, hammers, saws, pulleys, and other simple machines—and acquaintances will often exchange miniature gilded specimens of these instruments, purchased from gift shops, in lieu of other ideas for presents; the act of exchange is sometimes believed to imbue these otherwise useless ornaments as lucky charms. To have "carpainter's wealth" or "a house built with golden nails" are colloquialisms suggesting someone knows many people but has few if any real friends.
