This Ars Magica campaign was set in 1220 in the city of Alexandria in Egypt. Some material is available on the Web, including the original premise, other campaign guidelines, and the GM's notes on the campaign, after it folded.
The members of the covenant, both the elders (all NPCs) and the younger, new blood, magi are listed.
The covenant's library is also available, as is the cgi-driven "library card", used to keep track of which character was studying from which book in a given season. (There's no clever interface to this, rather the flatfile database was manually updated.)
Finally, some character sheets, done with cgi to generate a nice layout from an easily-maintainable flatfile:
For the curious; the subtitle for this campaign stems from the location of the covenant in the city of Alexandria. It was built in the ancient and extensive cellars of a still functional bath house.
