Dark Light Dwellers (UN-D-7983)
Unfortunately, all attempts at communication with these creatures have so far failed - They do not seem to recognise humanity as a sentient species and have never attempted any interaction.

However, the Guild regards the Dark Light Dwellers as a benign species and no threat to humanity.

Next time you see a movement of shadow from the corner of your eye, but find nothing there, there's a good chance that you've been fortunate enough to encounter one of the most common but extraordinary inter-dimensional travellers known to humanity.
