"That's why her hair is so big. It's full of secrets!"
The most prominent feature that students and some staff are most likely to notice about Gretchen is her hair. It towers in elegant piles. There are numerous rumours as to how she manages to keep it in that style, ranging from advanced cosmetic illusions to the outrageous claims of imprisoned devils to hold it up.
Other than that, she looks like an ordinary pretty elf girl. Her hair is a pretty blue green. Her skin is very fair and tends to glow dim pink when in the dark.
