While many historical þereminian cultures have had shared folklore or mythology ultimately based around dealing with plurality, the Cold Sea region is notable for having one of the longest-lasting and most consistent sets of folklore around the topic. "A visitor from through the wood" is believed to be the origin of many of the basic concept behind the historical Cold Sea belief in visitors from another world, although many important aspects of the shared setting did emerge in later works.

As with many historical works, finding the single 'original' version is often quite difficult. Luckily, in the case of "A visitor from through the wood", one written copy of the story was registered with the Archive significantly before other attested versions started appearing, making it highly likely that this represents something close to the original version of the tale.

The story is about a young boy — Morlhav — living in the woods with his mother. When she dies, he is caught between a need to reach the nearby village — because he cannot prepare for winter by himself — and a fear of leaving the house to travel alone through the woods. One of the fair folk — Érdamman — observes him from the other place, and knows that without assistance, he will perish. So his observer makes the dangerous decision to travel to the ordinary world in order to help guide the boy through the woods and to safety.

The story alternates viewpoints between Morlhav making his way to the village and Érdamman making his way to the mortal world, with Érdamman's interludes serving to teach Morlhav lessons about navigating, or simply to raise his spirits and encourage him to press onward to safety.
