Ok, instead on spamming this thread, if you can't contain your whiny crybaby attitudes and see that the plot is far deeper than you could think, PM me, and I will tell you exactly what is going on in the simplest terms possible. But I will not give you the whole plot. Stop being lazy, and start putting things together. This is an -advanced- quest, not like the simple ones ingame now. There are layers on top of layers here.
Xillix being cured is probably one of the biggest clues of all. Think like your characters, not like yourself. See the world through their eyes for a moment, and react upon it. The RP is FAR from over. I have let Xillix in on a few of the secrets, but not the entire plot. Within the next few days, you will see why.
(this was not directed at Kalika, who honestly seems to be trying to figure this out. Hats off to you....but I am not going to make it any easier. This 'quest' was not ment to be solved in a day or two. The ending is open, and will depend on what you folks do.)
