The answer Lissa gave for the third trial was a nice sentiment, but it was silly. Here's MY answer. I know this is short and barely a fic, but it's what I would have said in her place; and honestly, it makes a lot more sense, and shows a lot more consciousness of what ruling means. You can give everything to your people and they may still not accept your rule, after all.
There is nothing in the material world that makes a queen - not even the land in which her people live - so there's no need to acknowledge that angle further. As for the immaterial world, qualities of character tend to come to most minds: Wisdom, strength, courage, honesty, integrity, tolerance, patience, kindness, intelligence, honor…but these are not what a queen needs to rule her people. Perhaps, if she possesses them, they will help her attempt to do what is BEST for her people, but that is not the question. In order for a queen to LEAD her people, at ALL, in ANY direction, be it just or unjust, she must have their support, their faith. A person cannot be a leader if no one will follow her, no matter her title. Indeed, it is the people who give the title meaning. In short, what a queen needs in order to lead her people is the people themselves.
