Space Wolves: Help with puppy fluff pt1.

Hi, at the moment I am trying to decide on some space wolf fluff but I am struggling to find background on each individual great company. Please can you help me by either commenting or commenting with a link to where I can find out. if you help then I will link to your blog in a thankyou post. So, I would like some back ground on each of the great companies and any other useful bits. tell me what i need to know. I have already found out about their organiseation and Leamn Russ but not much else.

Sorry it's only a short one.

Thanks for reading (and hopefully commenting),

Jacob.
