Reimu recalled seeing imp tracks at the fork in the road back when she made the choice to go right.  At what point the imp tracks disappeared she wasn't sure.  It was only when she stopped to debate going back that she noticed the lack of foot prints.  In fact there seemed to be less dirt and dust this far down the path, and more bare rock.  Making the decision to continue on down the path took a while, but eventually the path opened up onto a rock ledge in a great cavern.<br/><br/>The cavern below was huge, and even with the dim light of the cave rocks, Reimu was unsure where the far walls of the cavern were.  Nearby to the left, a small waterfall spilled over the edge of the cliff she was standing on to spill into a pool far below.  Off to her right the cliff seemed to be carved into the cavern wall and began to descend to the floor of the cavern far below.<br/><br/>But most interestingly enough there seemed to be activity in the cavern below.  Far off in the cave a large city of sorts seemed to be thriving.  Made out of stone and carved into the rocks of stalagmites the town had a defensive wall that curved around to meet the western end of the cavern.  Outside of that wall what appeared to be vast farms of mushrooms.  It was very hard to tell from this distance, but it looked like dark skinned humanoids were moving about the mushrooms in the cavern below.<br/><br/>An old legend came to Reimu, a subterranean group of black skinned elves that were as evil and cruel as they were perverted... if the legends were true, of course it would make sense that they came from the demon realm.  Drow.<br/>
