Oh，there is a way other than mind hunt, WHICH WILL BE AVAILABLE IN THE NEXT VERSION: Ask help on your ally, a third nation, let them siege and patrol your castle to get the pan or vampire count or whatever. Unfortunately, in the current version the unit that been patroled out will just became "defend" and there will be no battle unless the siege is over, just like barbarian attack during sieging. So you just need to change "defend" command into "hide" and all their effort will be in vain. Hopefully, this will be changed in the next version according to the progress page.

And seems the free spawn will only generate if the province is your dominion OR under your control.
