Warlocks cannot find slaves in an empty province any better than anyone else.

there are three checks to pass:

roughly by memory they are:

1. 40% * blood level to find slaves.
2. Pop/5000 % that it worked.
3. Unrest / 4 chance to for them to say.. screw you.

So, in an empty province warlocks fail just like anyone else does. Warlocks are just good blood hunters because they always pass the first test.

also shows why you don't give them SDR's.
