However, their true numbers arent exactly known (granted they are probably lower than that of an Asartes Legion) this is not premise enough to write them off entirely as a possible missing legion. The Space Wolves only had one failed successor chapter with their gene-seed and their numbers remain at only between 10,000-12,000 Battle-Brothers. Now that is still a very large force but nowhere near what it would have been during the GC or HH eras.

Also I didnt say that they were exiled I simply offered it as an explanation for their lack of communication with the Greater Imperium. They operate outside the Imperiums borders which could arguably be outside the Astronomicans area of influence and their mission is too wipe threats before they even reach the Imperium. They are also fiercely loyal for such a bloodthirsty savage chapter, it seems that they would have long since gone over to Khorne.
