Well, first off, there's a Forever Knight Wiki. There's a section for the wars, though most have only skimpy entries. (The entry for War 14, however, was written during and after. It is absurdly long and emits a fair bit of steam.)

There is a Forever Knight Website Archive if you want to deep dive into ancient history (1998-2004 or so). So many little sites were going to go into oblivion that an effort was made to preserve them. This includes the main fanfic archive, www.fkfanfic.com, whose history has a looooong Fanlore entry.
