Instinctively, you know you are going to be discovered if he gets any closer.  You aren't sure how you are going to go about escaping the other two, but you are gonna have to kill this one before it gets any closer.  Without warning you lunge forth and put your short sword through the creature's belly.  You were actually aiming for the heart and the creature moved so I guess that says something about your swordsman skill.  Nonetheless, it proved effective at killing the creature.  You waste no time at all in bolting back up to the original chamber with the campsite and the other two will round the corner any second.  You need to make a decision FAST! 

 
The large pathway (on the right wall as you enter) is now inexplicably barred but you can still run back outside the cave or down the passageway that was previously inaccessable due to their presence.  The adrenaline floods your body and your survival instincts take over.  You immediately decide to...

You run Outside The Cave

You run outside the cave and around the corner.  You are back on the plateau overlooking the village.  Your heart is beating fast as hell and you are clutching your sword so tightly you will probably have blisters.  Fortunately for you, the humunculi have chosen to run down the path behind their campsite.  You wait outside the cave for a few hours and still they haven't returned from the passageway.  Perhaps they have chosen to travel further in to pursue you?  

 
You return to the cave's interior and are standing at the campfire.  The large passageway on the right side of the chamber is still blocked.  You peer down the passageway in front of you, the one the humunculi chose to go down and you wonder what lies beyond its depths.  However, as you look left you remember there is still an as yet unexplored passageway down in the cavern where the humunculi nearly overwhelmed you.  You aren't going to find the Craxil by standing around here so you are going to have to decide where you want to go from here.

You follow The Path Behind The Campfire, Where The Two Humunculi Went

You chose to take the passageway behind the campfire.  If these creatures are protecting the Craxil, or at least serving him in some sense, it would makes sense they would head in this direction.  You get the strong scent of burning animals or something like that and what you see next is COMPLETELY unexpected.  Instead of seeing the two humunculi that ran down this passageway earlier, you are standing directly in front of some kind of hovering demon whose gaze is fixed directly upon you!

 
This thing looks like a large floating eye with multiple smaller eyes attached atop its head.  You realize this thing is a beholder and soon you find yourself paralyzed in its gaze.  That's what you get for staring into its eye I guess.

 
"Answer me puny one, why are you here in my domain?"

 
You are too terrified to answer, but this creature appears to grow irritated by your silence so you muster all the courage you've got and speak up

 
"I'm here to slay the Craxil" you proclaim, terrified of how this creature will respond to such a bold statement.

 
"HA!  Amusing little one, someone of your strength doesn't have what it takes but it would entertain me to see how you die in the Craxil's mountains.  Answer this riddle correctly, and I will permit you to continue through to the other side of my domain.  Answer incorrectly, and you will share the same fate as your former pursuers.  Are you ready?"

 
"Did he kill the humunculi?" you think to yourself...

 
"As ready as I'll ever be" you squeak.

 
"Very well!" it bellows, clearly enjoying every bit of this.  "I am a vast canyon that spans beyond sight.  I am without end and have been a part of every man whenever there is trouble.  What am I?"
