Dragons are highly-intelligent reptilian creatures that—from a human perspective, at least—appear to live forever. Many different varieties of dragon exist, each with their own unique qualities, habitats, and behavior. Adolescence in dragons is usually marked by the growth of a hatchling’s wings, although not all breeds of dragons grow wings and some breeds have other traits that indicate the beginning of maturation. In Galsreim, dragons and humans coexist peacefully.

Aeroscorn absolutely LOVES to eat lemons. Lemons, lemons, lemons--that's almost all she ever talks about. For some reason, she holds a serious grudge against life. She often roars to the sky that she will burn life's house to the ground, with the lemons.

The other dragons try to stay out of her way whenever she has one of her lemon rants, but truthfully it is no use. The Separator Tinsel will track down every dragon, give them a lengthy talk about life's manager, and will then tell them not to make lemonade.

Needless to say, the others consider her crazy. All of them, that is, except six dragons; Wheatley, Rick, Space, Curiosity, Autumn, and GLaDOS. While the former five all tend to just walk away, for some reason GLaDOS always gets very cheerful and excited at the concept of blowing things up with lemons, and could be considered Aeroscorn's 'friend' in lemon craziness.
