The mists of time are probably the most dangerous place in the other world. The easiest place to become lost in. To pass through them you must walk in a straight line whatever happens; whatever you see.
When walking through them you see the future the past and present, glimpses of what has been and what is yet to come. They will show you others and yourself.
You may be hindered by soles who are trapped in them. And once trapped there is no escape.
