Seelie and Unseelie

Based upon the interpretation that hags are rejected by both courts, both courts are focused on beauty of all sorts. They are described as courts of Winter and Summer, which begs the question of fall and Spring.

The courts are both very similar, being like sides of a coin, or twins in a fight over the same thing while claiming that they are not similar whatsoever. 

So.... One is upbeat, the other is intellectual, but both are petty and have the same type, and same wants.
