@Raineh Dazemmmm yus I see your point.
There's not really going to be any overlap since we're literally the other side of a country.
Sapient undead still for the most part look like they're alive; since they come back at the moment of death and have explicit regeneration.
An intelligent undead that isn't would be a lich and you can imagine how poorly a terrifyingly powerful evil necromancer fits in. :p
