Soulless need corpses for reanimating.

Ashen empire gets better undead at castles.

Soul gate gets free priests at temples sometimes.

There should be a table in your manual displaying how much each undead and what kind each kind of reanimating gives you.

If you make make an arch bischop your prophet with ashen empire, he'll reach level 5 unholy and can cast power of the sepulchre and reanimate cencors.
