My Lord Emperor, when is your most loyal son, Leman Russ, Primarch of the Space Wolves coming back? Not to like lead us or anything, he just sounds like a blast to drink with.
First of all, if you have any hope of drinking with him; abandon it, you will not survive. And as for the question, I do not know when he will return; but when he does, I am certain that either he will come charging victorious out of the Eye of Terror. Either that, or he is on Fenris where no one ever looked. I would not be surprised if it is the latter.
