Well I dont know about the rest of the crew in this game, but if as Norfleet said research is difficult and it is turn 20ish, then you can bet
- his VQ is armed with bupkes
- his dominion is mediocre at best

Do as Gateway suggested and screw up his provs, preferably those with temples and high coinage; even if you kill a few blood hunters, that's fine.

A naked VQ is not *that* scary, especially in your own dominion. Go for his provs in which you think the VQ is not, and let her come to you. Your PD is kinda helpful here since it's X-bows, just keep a few infantry folk around; numbers will help, dont go for the knights right now.
Once his blood economy and money is dented, he'll be hurting.
