After some thinking and observations from my newly started EcoCrim, I have come to the fact that the Enigma Forest originates from an Alien Lifeform.
The things I have found as possibly evidence for this, is the following.
1: The Map of Central Artery Valley reveals strange circles and lines, shaped almost like the Earth phenomena "Crop Circles" populary connected with UFO`s. Of course, CAV is far away from civilization, and the chance for bullies or workers that want attention going to the dangerous place just for fun is unlikely.
My theory on this, would be the work by the Engima`s themselves, a way to contact their relatives and show them they have landed.
2: The Forest it self. Unatural, too symmetric and complicated to be a work of the nature it self or Omni-Tek. The Trees are living creatures too, something we only see here.
3: The Enigma beings. They seem to be similar to supposed Aliens when mankind lived on Earth. Their look, which is nothing like anything else on Rubi-Ka, can only be seen as otherworldly.
These three points is what I have currently figured out as possible proof of Aliens living active on Rubi-Ka, It is my hope that we will discover more about them and maybe find out where they come from.
There has been no visible progress in Enigma Forest since I started investigating it, but I will keep the case open and shed light upon any new events. Any form of threat to mankind or fauna on Rubi-Ka must be stopped before it can go too far, and I have yet to be sure of what these Enigma`s are planning.
Until then, take care.
