The fog does not drift or change, at least not that has been identified, meaning the boundaries of the world are absolute. Those who venture into the fog are not always lost, but find themselves stricken by strange circumstances. First, the traveler has no control over where they will emerge from the fog, meaning that one is just as likely to emerge in the middle of the ocean, an arctic tundra, or a sweltering desert as they are to emerge in a more hospitable place. Coupled with this, fog-travelers are generally lost in the fog for a minimum of a week, sometimes for as long as several months before reemerging, with the occasional traveler not emerging at all. Fog-travelers also emerge showing visible signs of wear and tear from their time within the fog, though they possess no memory of their time in the fog, and in fact can detect no gaps in their memory. For the traveler, only an instant has passed between entering and exiting the fog. Despite the lack of memory of their time, fog-travelers all report residual senses of fear or dread, or the feeling of being pursued for some time after emerging again, though so far no prolonged ill-effects seem evident.
