So I think I did a stupid.
I've been reading up on keys and things and didn't really understand them properly before (I'm pretty new at the game, started less than a month ago). So I was just carrying around the Master Keys to my palisade and chests and things, without a care in the world. I found a Beaver Dam, and didn't really know how dangerous it was, so I went in to explore, and couldn't leave to escape getting killed by the beavers inside (they just waited around for me to wake up when I was knocked out, and you apparently can't hearth home out of a Beaver Dam). So I died with my Master Keys inside the Dam. Now I made a new character to inherit this one since I didn't feel like starting totally raw. However, I'm now inside my claimed palisade, where my Hearthfire is, with no keys. So I can't get out. Am I just royally screwed and would just have to make a much stronger character outside to break in for my new character to get out?
