You find yourself standing inside a large clearing in Darkwood Forest, lovingly titled Darkwood Hollow. Its thick, heavy walls extend far below the dirt ground, and the top is sealed off with a strong wire mesh. The precautions are not uncalled for: Darkwood Forest is notorious for being filled with dangerous beasts of all kinds. You occasionally hear unearthly screams from the heavily shadowed forest; but, more often than not, it is eerily, deathly silent beyond these walls.
Inside, though, is not nearly so bad. The thickly-foliaged trees where cleared away long ago, when the base was used as a research facility, so Darkwood Hollow is much brighter that the rest of the forest. Sadly, "much brighter" doesn't mean a lot compared to near pitch-blackness, and the heavy cloud cover of the area keeps it suspended in heavy gloom. Despite this, grass has come to replace the decaying leaves that used to serve as the surface underfoot, and many different kind of creatures of romping, eating, and relaxing on the grey-green carpet.
Perhaps you should go visit them?
