Lets look at this another way. The game they are playing is an obvious reference to the game of Risk, except their version has trap cards and such. Anyway, the figures in Risk are all modeled after soldiers that would have fought each other at least a hundred years ago. Now looking at the game they are playing and the level of technology Vale currently has, it makes more sense to think that the pieces on the board represent normal run of the mill knights.

Now going from what we know of the history of the world, there have been a few wars and we know that Weiss' grandfather started the SDC. If her grandfather or even her father had any interest at all in these wars, they may have a suit of armor on display in their home, causing it to manifest in Weiss' dreams.
