Ok, so I've just updated this with things that people have been asking for, as well as some things I thought new users might find useful.
Let me know if you see something missing (I'd like to get some definitions for Einherjar, Assault, Campaign, Salvage, and so on put into this post as well.)
So, thanks for any input, I'll be gone for a few days so I won't be able to add in anything more till later this evening or Monday.
