[X] You shake your head in denial. This, just now, was wrong: There are better ways to do this. YOU know better ways to do it. But it is undeniable that you do know no a lot, about almost everything else. Your cult has an established structure and is growing, and you have a position of power within in, but after tonight, you do not intent to stay forever.
[X] You nod, a grim understanding coming to you: Equestria is in danger, and something must be done about it. You have not reached the point where you think a line has been crossed, not when considering what you have just seen. But you will keep that line close to your heart, for you know that you will lose something the day you cross it, and it is not something you wish to lose if you can avoid.
[X] You realize that you had a smile on your face: Princess Luna is weak, but she still bears immense power. She is like a spoiled child, unaware of what she could do if she had the will to, so perhaps the term "Princess" really is fitting, after all. You will take her power, or you will take her, and then you will take what comes next. Everything between here and there will become means to those ends.
[X] You realize just how right your Master is: Your Master is right, and it is a blessing that you have met Copper Secateur and, through her, been induced into the cult. You must defend Equestria, no matter the cost, and only by furthering your cult will that be possible.
[x] You loudly decry your master. A moment too late, a second after his presence is gone, but you are heard by everypony else: What you did tonight was wrong, and your Master either knew of the consequences, or he is not wise enough to be worth following. But regardless of what he is, you will actively oppose him.
[X] You left. You broke. You galloped away, screaming, and you arrived home limping, your leg cramped with debilitating pain. No more of this. No more.: You do not want to have anything to do with this anymore. The ritual was too wrong, the memories of Princess Luna too vivid. The worms were too frightening.
