Well, Midaski, of course we should discuss the revenues! A tenth is more than fair, supporting the valiant efforts of the Kislevites fighting chaos lead by the mighty Midaski! And as far as I know there is nothing in the relevant tomes of Sigmar that prohibit you having the company of witches, as long as they are Kislevite witches that is. We should surely chase down other witches, but nothing is said specifically of Kislevite witches.
It also speaks of the power of Midaski that he are able to tame TWO witches! Now he is surely blessed!
But of course Rufus will be honoured equally. As I said we have an infirmary of Shallya and also an Inn for Pilgrims that needs a protector. So St. Rufus is hereby ordained as the protector of Inns all over the Empire!
