RPG Epic Encounter Maps by The Red Epic

I actually think the lack of ice in the house is a good thing. It means the map might just be someone house but it is in the winter, as opposed to supernaturally frozen inside and out. You can get away with either description to the PCs about the map based on the one in the OP.

Edit: There are snowy footsteps in the mansion though, if you look carefully at the second floor.

Now that snowy mountain pass is one hell of a fine map and I think I've found the battlemap for some Perytons with that one (flying creatures and changes in elevation are a killer combination)
