Since I’m running my family campaign through the Cairn of the Winter King adventure from the Monster Vault, I prepared everything in MapTool (my wife and I are in Colorado; her brother and his wife are in Texas, so we play online). I figured I might as well put the adventure out there to share.
This campaign file was created in version 1.3.b66 of MapTool. If you’re looking for the maps independently of the campaign file, you can find them here. Enjoy!
