From the site:

Aeon Covenant (originally Phoenix Covenant, which was submitted to B.J. Zanzibar‘s White Wolf fan supplement web site in the late 90s) is my first RPG fan work; it therefore holds a special place in my heart. It has been updated several times, but is still extremely out of date. Although the entire site has been given a face lift, the text itself hasn’t been changed in years.

This is one of the supplements that has its own site design and so is being left where it is.

Note: BJZ’s site was formerly at mypage.iu.edu/~adashiel/wod; the gamingnerdsrus.co site is an archive.
