How Can You Find Something That Doesn't Exist?

I know its asking a lot that the first place I went would contain that which I sought, but I'm normally lucky! The cave stunk of mold and disuse (no one had been there for quite sometime, Valrya had a lot of hiding spots that none of her apprentices knew about and that she rarely visited).  The one that was close by had apparently been some kind of food storehouse combined with experimentation on animal flesh (at least I hope it was animal flesh). Now all it had was stench and rotten food (so like my place after I've been off on an adventure, seriously I've learned to never keep plants or small animals).  There were a few journals scattered about, mostly dealing with the food experiments and their varying successes (not a lot on the quil, but I did find what sounded like a fantastic barbeque sauce recipe).

I was about to leave when I heard a snorting sound.  At first I thought it was the wind (yes I'm one of those guys, who thinks everything is the wind, loud explosion? Probably the wind), but then the snort was accompanied by a slam of something, and the wind normally does not grunt and slam something (one or the other never both). I turned in the half light of the cave (I'd brought a torch and lit some lanterns inside, yes I'm terrible at describing where I visit deal with it) and saw black and tusks, and then I was driven backwards by the beast.  It had such fury it drug me straight out of the cave and into the sunlight beyond (this was also through a couple doors, let me tell you I was picking splinters out of my back for about a week). Into the light of the day I could see the beast was some kind of boar creature, its flesh looked scarred over from where Valrya had been picking off pieces for her experiments (which explained the anger, though I have no idea how this creature lasted this long probably dark magic).

I managed to get my sword loose and plunged it into the beasts forehead, all that seemed to do was piss it off more.  I turned around to see I was about to get rammed into a rather large tree. I worked like mad to fre myself and slipped off the creatures tusk just in time before it slammed into the tree and effectively gutted itself (perhaps its intent the whole time? I mean I'd want to die if I had been used for some weird flesh experiment). I was pleased to have survived, though still at a loss for finding that stupid quil.  I mean Valrya had safe houses all over, and some of them had been raided (by Morley and others, so the idea of finding the Quil was one of madness to begin with).  Still I claimed I'd find it, even if I was beginning to doubt it was ever a real thing to begin with.  Thinking back on this, I've done this quite a few times in my career.
