The category The Great Library
The Category: The Great Library includes all the works and knowledge of the Atysians. It brings together the main branches:
- Category: Science and technology: various "scientific" theories, but also rantings, sometimes at odds with the Lore. This category also contains all culinary, floral... arts
- Category: Literature: player tales, various narratives, biographies, etc.
- Category: Society: guilds, courtesy, protocol, commerce, housing...
- Category: Homins: all about characters living or working in Atys.
- Category: History: stories not yet in Category: Official Lore
- And finally all the unclassifiable topics in the Category: Bric-a-brac
It is at least in one of these branches or sub-branches that the created documents should be classified so that they are easily found by homins looking for reading or information. It is not uncommon for an article to fall into several categories.
