A Vampire in the Elemental Plane of Water?

[LurkAway]

To me, all of this says that it the issue of water is strongly tied to contrasts - water runs through and off an area, a contrast to the static land. I would normally say those conditions don't exist on the elemental plane - there is no earth to be in contrast to.

[Lighbulb!] The portal between the Prime to the Elemental Plane of Water is the contrast, the barrier that cannot be crossed.

Thus vampires cannot enter portals into that plane. Let's say they're teleported. If it's truly an instant teleport (I forget the metaphysics), then I think the vampire would be fine (but might never leave the plane without a teleport back home!). But if it was a sort of instant dimension travel via ethereal (again, I forget the metaphysics) then I think the vampire would appear at the border between the elemental plane and the ethereal.

Thanks a lot for your replies!

I see there's no "official" answer to this, I'd assume someone on the Planescape setting would have put a Vampire, perhaps on the City of Glass?

If you want to know what happened, it was very disappointing. I had decided that the Vampire could not survive in the Plane of Water except inside an air-bubble spell or something similar. Of course the player didn't know about that, but he just assumed there was no way for him to interact when in the bottomless deep.
The vampire player decided to stay on the coffin the whole plane trip (and the party was feeding him inside a Mordenkainen's Mansion so there was no need for him to actually wake up from his coffin). I so wanted to see him turn into gaseous bubbles
