Explorers (non-orienteers) can have quite a challenging and (hopefully) interesting quest, as the following describes.
[This is possibly a SPOILER.]
The first strange thing that explorers are likely to notice is that some rootstocks (upturned tree roots) have fragments of a small map attached to them. Putting the fragments together reveals an island to search for on the main map and travel to. If all the fragments have been seen something will happen on arrival at that location. There will be a clue as to where the treasure chest lies very near there.
There are several other diversions that may be encountered along the way and which may or may not be worth looking into.
Also scattered throughout The Forest are some posters written in a simple cipher which the explorer may want to elucidate. When decrypted these posters give clues about various things in The Forest, including how to get into certain places. It is not essential to read these but it could save some time and effort. The cipher appears on something else too, so it is useful to understand it.
The treasure chest has a note (in plain text this time) indicating how to find a particular building. It also provides a key code for entering the building. Do make a note of the key code. Buildings all have key codes which must be typed in for entry. There is a measuring device that can be found in many places underground. It will help to determine the key codes, once the explorer understands how it works.
Once inside a building there are posters on the walls which may help to explain certain things.
Buildings all contain a controller for a mechanism which is essential for the next stage of the treasure hunt but the mechanism will only work in that particular building indicated by the note from the treasure chest. (It is believed that there is only one building with that key code but since everything is randomly generated that may not be true.) The mechanism will reveal the target of the next stage of the adventure and make it possible to get there.
The next stage involves a dream sequence reminiscent of a certain film. The sequence ends at another machine.... (to be continued).
Further hints: there is a shortcut key that enormously assists the journey from the starting area to treasure island. The x and y positions given in the status line also may be useful. See the User Guide for more details: https://www.grelf.net/terrain.html
