[Scarmiglione]

Any undead or demon priest can reanimate undead, so any nation that has those, such as Lanka, can reanimate. You can also make a demon or undead unit your prophet. there are some summoned units, like mound fiends, that can reanimate. Pangaea Carrion Lords and Ladies can reanimate unique undead. one of the Sauromatian heroes can reanimate undead parthalonians. Probably more I'm overlooking.
