Humanity may not be perfect, but it certainly doesn't deserve the kind of death and destruction the Craxil has in mind.  You announce to her that you would rather die than support her in this plan.  You were terrified that this being might become infuriated and attack, but instead she calmly and slowly backs away... then looks to your sister.  Your sister looks back at the Craxil and you realize the Craxil has just given her a nonverbal order.  By now your sister's blade is unsheathed and she is coming at you. 

 
She fights with a furocity and intent that is completely out of character for your shy and reserved little sister, but her physical strength is the same.  There is nothing special about her swordplay technique either and you are pleased to see that you can block and parry her attacks.  Still, this is your sister, and you don't want to kill her if you don't have to.  The Craxil is obviously enjoying this and you can't help but think that if you could just find some way of killing her then perhaps your sister can be saved.

 
The Craxil is currently in her noncorporeal true form, but she has taken corporeal forms before when she was watching you.  You wonder if striking her while she's in one of these corporeal forms might actually damage her.  Alternatively, you wonder why a shapeshifting being with noncorporeal capability would even need others to spread the plague in the first place.  Perhaps she isn't immune like you once thought or perhaps she felt secure from it in her noncorporeal form.  Would you still need to get her into corporeal form for that first or could you try and give it to her while she's in her noncorporeal state.  Or perhaps there is some other way of getting your sister back to normal.  Unlike you, she knows some very basic magic.  Perhaps she will have something that will damage the Craxil in its noncorporeal state.

 
While your mind wonders to ponder these things, your sister manages to get a shallow cut across your right shoulder and you respond by kicking her onto the ground and stopping down on her sword hand.  You remove your sister's weapon and the Craxil moves in as if to protect its vassal.  You quickly begin to go over your previous ideas in your head knowing you will need to try something and soon lest the Craxil decides to attack first.

You challenge The Craxil To Take On Other Corporeal Forms, Then Infect Her With The Poison

"It is clear that I have neither the means nor the ability to complete my quest, so as a dead man I ask that you grant one dying wish" you proclaim.

 
"Throwing in the towel already?" she scowls, obviously disappointed that you didn't have some clever trick in mind.  "From your past exploits in my territory I thought you'd at least think of something to try.  What do you want?"

 
"I want to know how you were able to keep tabs on me during the journey.  What other forms did you take besides Brandolf and the old man?"

 
"I took many forms.  From birds, to rocks, to the very water you swam through to get past the orcs."

 
"Show me" you demand, "I want to more fully understand how I was bested before this ends.  Let me die with that peace."

 

As she's talking, she starts by taking the corporeal form of Brandolf the Bray and you seize upon the opportunity.  As rapidly as you can you grab a poison coated arrow, notch it in your bow, drawback the drawstring, aim, and release.  The poison arrow lands in her forearm and she promptly removes it and tosses it aside.  You fear she was unaffected by this arrow and she begins to laugh.

 
"It seems I misjudged you, you haven't surrendered at all have you?  Attacking me in my corporeal state... that does sound like you.  But I have the ability to reform my corporeal state just as easily as I formed it in the first place.  This is a simple matter of..."

 
She stops midsentence as if she somehow came to the realization of what you've done.

 
"That arrow..."

 
"The same stuff you gave me on day 1.  It looks like I managed to complete this quest after all"

 
The Craxil bursts with laughter as if somehow impressed with your creativity or perhaps the irony of the situation.  She doesn't stop laughing even when the nausea and vomitting come.  You can tell her power is waning because you sister suddenly regains control of her facilties and runs to your side.  The Craxil laments that the beastmen will no longer maintain unity after her death and expresses genuine concern about their well-being.  You aren't sure why, but you promise to try and convince the human leaders in Mihtana and Lima to recognize the importance and advantages of peace and even integration of beastmen into civilization.  She smiles and then the light that made up her corporeal being goes out.

You continue The Story

Unfortunately, this story takes a tragic end for your sister, who remains a carrier for the plague even after the Craxil's death.  You explain to her what the Craxil was and what it planned to do.  She backs away from you immediately as if not wanting to infect you.  In fact, it dawns on both of you that she will never again get to experience the physical touch of another person in any way ever again without killing them.  In a deep state of sadness, she decides to remain in the wilds as a hermit, embarking on a quest to find a cure for this condition.  You want to stop her but in all honesty, you cannot possibly think of anything better for her right now and bringing her to civilization would be a bad idea right now.  You wish you could hug her or comfort her somehow, but you both understand why you can't.  Instead, you wish her the best of luck and hope she one day finds what she's needs.  From this point on, there is not a single night that goes by for the rest of your life that you don't pray for her.

 
With the death of the Craxil, the doors that sealed behind you are no longer fixed.  The infighting amongst the now disunified beastmen makes it easy for you to get through unnoticed on your way back to the village.  Along the way you see grippli attacking goblins, kobolds fighting amongst themselves, and the orc patrols seem to have raided numerous humunculi settlements.  The large, unified force they once represented is now thinned out considerably, and although the journey is long and your rations are low, you eventually make it back to the village.

 
The villagers are shocked to hear that the Craxil is dead and you tell them all about it.  Some believe you are full of it and think the Craxil still lives.  Others admit they bet good money you would die.  You were right to assume they'd have redistributed your property under this very assumption and it takes some doing getting it all restored.  Unfortunately, they decided to slay your friends Oinky and Snout for ham while you were away and for the first time in your life you chose not to take it lying down anymore.  If this journey taught you anything, its that you are going to have to demand respect if you hope to get it.

 
However, this journey has taught you a lot more than that.  As promised, you travel to meet with leaders in both Mihtana and Lima so that you can try to convince them why peace between the humans and the beastfolk might actually be beneficial.  You explain how the Craxil was able to rally them together and organize them and how some of them demonstrated a higher level of intelligence than you originally thought them capable of (i.e. - the kobolds extensive mining techniques and the goblin's tinkering).  Unfortunately, despite your best efforts, the world is just not ready to view them as anything other than dangerous savages to be on guard against and you realize that this is how it is going to stay.

 
Eventually you return to your farm and begin shoveling out all the pig dung that had been piling up in your absence.  As you are working, a girl you took notice of at the local tavern looks over to you.  You smile with confidence and she smiles back and suddenly you think... this might not be so bad after all.

 
CONGRATULATIONS!

You've found real ending #2 of 2.
