According to Norse mythology Gerd is a frost giantess whose beauty is compared to that of Freyja. She 'seemed to be made out of light' and 'when she raised her arms everything grew brighter'. However, I imagined her to be absolute Freyja's opposite. Freyja is a goddess, whereas Gerd - giantess (although not all giants in Norse mythology were huge and hideous). Also Gerd is thought to represent cold winter months. So having that in mind, I decided that Gerd should be of a darker nature.
