Warcraft America

I dreamed that most of the American continent had been wholly transformed.  It followed the MMO mechanics of Warcraft in the dream, but did not share its geography.

There was an enormous stone construction that was a sort of building or temple, very narrow and acting as a dividing wall in the western part of the country.  On the north end, things were fairly desolate.  A sort of rock quarry with sloped walls.

There was a lake in which the temple had been built, and one could swim through a narrow gap at the base of it to reach the southern parts.  The lake was very deep and had stone sculpture work extending into the lightless depths below.

On the southern end, a sort of posh resort or hotel or something overlooked two beach-front towns, each in a simmering rivalry with each other.  They possessed artillery devices of some sort which were leveled at the other.  In the hotel was a cast of characters, including some member of the aristocracy who had been known to have had affairs, and his wife and a few others.  Secretly the aristocrat either controlled a boss-level sea monster that lurked in the lake, or in reality was the monster.

Far to the south, where what must have been California or Nevada, the land was actually snowy and frozen. There was a gigantic church there, under a geodesic dome sort of structure.  It had smaller outlying buildings similar in function and was very desolate and remote.  Beyond it were mountains that led up to a plateau on which spotty snow coverage also exposed farmable herbs, and in the rock face of the slope leading up were mineral nodes.  Unlike the usual ore spawns, these were not identifiable by type (just "mineral") and were much more deeply embedded in the rock than normal.

Someone wearing glowing paladin armor was attempting to herb at the same time as me.

To the east, a supermarket of massive proportion in the middle of a frontier town.  A vampire with telekinetic powers and a straw (with which he'd suck blood from peoples' arms) was pitted against the night watchman of the supermarket, who was a fundamentalist or fanatical sort.
