The information requested concerns another cosmology from that of the dominant native one in Magisteria. "Holy water" as you describe it is utterly meaningless within this world.
However, to your broader question, there are equivalent forms of magic that oppose the undead and/or demons or other associated dark forces. Don't count yourself too comfortable; all must adapt to the milieu and cosmology of this world. While the rules of your own world may guide your adaptation, do not lean too heavily on the assurances of what you have always known or thought you knew.
