Lorelei is a white unicorn, who when first showed up at Ravenswood was described as a "monster" by the refugees. All they could see of her was blurred colours running through the trees. Emily finally got close to Lorelei, realizing she was hornless. Lorelei soon regrew her horn and later bonded with Emily. Lorelei gave Emily her horn, and it became Kara's jewel when she stole it for expert singing ability. Lorelei later became a teacher at Dalriada's Unicorn Academy.
Lorelei was inspired by Sunstar from Princess Gwenevere and the Jewel Riders.
