As the subject states, I was curious as to which of these skills you guys decided to put knowledge of the Fallen under. Both make a certain amount of sense, as Adeptus Astates covers the some of the mysteries and rituals of the Space Marine Chapters, where as Traitor Legions covers those who have fallen from the Emperor's Grace, how it occurred, etc.
I was just wondering as a player has asked me which would cover knowledge of the Fallen in a game I am GMing, and wanted to know what your opinions were. Personally I was going to go with "Traitor Legions", since it covers all the Traitor Marines, and in XP terms is more expensive, therefore suggesting that the info covered by that skill is rarer and/or more valuable. Obviously any rolls for in-depth knowledge of the Fallen would either be vetoed by me, or be subject to a hefty negative modifier (the character was only a member of the Ravenwing, and so was only told the smallest amount of info on the Fallen (in that some Dark Angels decided to spit on their oaths and went to serve Chaos, and that he helps hunt them down - he doesn't know the why/what/when of the nature of the Fallen really).
Cheers one and all!
