OS-tan Annex Project
The OS-tan Annex Project was started on September 16, 2006 by former OS-tan Collections member C-Chan to create a OS-tan 'universe' to include new OS-tan characters and backstories. The Annex Project is by no means official but strives to integrate the new OS-tan characters and backstories with those of other OS-tan artists while still staying faithful to the original OS-tan canon and the work of other artists.
In the Annex Project, OS-tans are grouped into factions not to force political separations on them but rather to better organize them and the storytelling elements and that it would be much easier to remember an obscure OS-tan if she has a group representing her.
There are 9 current factions plus a category for deceased OS-tans, and Wanderer Class for unaligned OS-tans making for a total of 11 categories:
- Windows Family
- House of Mac
- Binteeji Renmei (Vintage Federation)
- Anti$oft Coalition
- Linux/Unix Consortium
- User Space Gang
- The DOSSE
- Mainframe Guild
- CIOST (Confederation of Independent OS-tans)
- Wanderer Class
- Deceased OS-tans
But since the world of the OS-tans is constantly changing in the Annex Project storylines, there have also been some former factions including:
- Apple Family (name changed to House of Mac when Apple II-tan retired in 1993)
- Microsoft-IBM Family (broke up in 1990)
- Commodore Family (disbanded in 1994 right after Commodore's bankruptcy)
- DEC Faction (disbanded in 1998 when DEC was bought out)
The Annex Project thread became obsolete with the debut of the OS-tan wiki and the thread closed down on July 9, 2007 but the Annex Project still lives on and being continued as new OS-tan characters and backstories are still being developed.
