I wrote a guide listing all the Artifacts, Knights, Ladies, Skills and Traits for King Arthur.
You can get Version 3.1 here: AKLSTv3_1.txt
Note 1: This is for the original campaign ONLY. It does not cover the Druids and Saxons expansions.
Note 2: The guide is complete, but please tell me if you see anything I missed.
What's new in Version 3.1:
Added missing artifact acquisition information.
Added the artifact Banner of Chuchulainn to the guide.
Added the knights Gal and Morold to the guide.
Added the lady Nimiane to the guide.
Corrected the name of the Banner of Persistence.
Corrected the stats of the Banner of Deepwood.
Constructive criticism is very welcome.
