The Throne
Houses who "sit the Throne" are the current winners of the Game. They are esteemed, mimicked, and courted in all things, and they have social currency to spare. Since it takes social currency to get there, there are some Houses that rise to the Throne over and over again. Generally speaking, no more than five Houses ever occupy this place, and there are never fewer than two who do so.
The Court
Houses that "bide the Court" are well-regarded, even if they're not on the very top of everything. These Houses are the most dangerous to those that sit the Throne, for they are hungry to take that position for themselves. There are usually anywhere from ten to twenty or so Houses that occupy this spot.
The Body
Most Houses occupy this position in the Game - they fail to stand out in any way, blending into the seething morass that is the population of little nobles in Waterdhavian society.
The Dregs
These Houses are the true misfortunates within the game. They are at the very bottom of the heap: ridiculed, scorned, and ignored. Those Houses that occupy this place are often those who have either earned the continued vehement scorn of one of the Throne Houses, or they are a House that actively ridicules the notion or has made enemies of the other Houses in some way.
