Edge of Darkness

Hi guys,
I walked west from my starter location on Jamestown (alt name: Mina) and found myself at the edge of the darkness. It was a dimly lit area and my humours were all normal (they average around 8 since she's fairly new). Since I don't know how to find coords on the map, I don't know exactly where it was but I can tell you it was grassland and the spot I created my new lean-to is in between a game trail that leads west into the darkness and lime deposits. I wandered all over the area exploring and leveling skills. I walked north, then west around a lake. Once I got far enough west, I noticed my humours were decreasing (I never saw the you should go back notice I saw once when I wandered into the darkness with my main on Plymouth). I quickly dropped everything and ported back home. All was well. On my next hike, I traveled north again and then east around the lake until I got pretty much all the way around it and got to the darkness again. I ported back and was fine, chopped up some logs, then logged out -- note: my black bile was low since I consumed remaining inspirationals to empty my pack, and my phlegm was low due to the wood chopping. The next morning, I logged back in -- and my humours start draining quickly and I got knocked out. Twice. Remember, I'm back at my lean-to where all was well. When I came to, I decided to quickly port to Jamestown, eat food to regen humours, went back home, and grabbed my dropped logs. Humours started draining again. I ported back to Jamestown, ate some more, went back to retrieve my stash from the lean-to and then all was well again. I decided to move on. But I have to ask, is this the intended behavior? Doesn't seem right.
