Kislev's Queen has just finished gaining the allegiance of most Kislev's towns but by no means does she have complete confidence of her nation.
She won't support Makari on what looks like a risky, dangerous and pig-headed gamble. at least not publically, for fear it will cause instability and unhappiness (after all, it's like War with the Empire and who wants that?)
That and she doesn't like her less-than-Tzar-material offspring. So he's alone, just his house troops, the men of Raknov and whatever mercenaries he can find.
Cheers.
