Because I'm to lazy to search through all of them. Here is the file that contains the infocards that are in 4.86 right now. All rumors, NPC names, base names, news stories (I think) should be in it.
This is the raw file, it does not tell you where the infocard is used nor who uses it. I couldn't find a infocard editing tutorial on these forums so if I have some spare time I'm going to make one.
