These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Green Rider
Fan-Preferred Couple: Karigan and King Zachary, to the point where the author (in good humor) rather plaintively asked people to stop asking her about it all the time, because there is more to the story than whether or not Zach and Kari hook up. (She remains mum on whether or not they will.)
Moral Event Horizon: Mirwell is first known to cross it when he orders the death of a group of schoolchildren because they might be rivals for the throne one day.
