Isdrithir was known as the Prince of Frost or the Pale Prince, and was an archfey of the Court of Vespera and the Court of Avyond within the Chimerazon. He rode the line between the sunset and the night. In Fey politics, he flew both flags and was recognized as a representative of both regions, though did not definitively declare for either. He embodied winter, a heavy snowfall - expansive, deep, inescapable.
Isdrithir appeared as a gaunt, pale blue Elf with long, straight white hair with piercing blue-white eyes. He often looked severe, but spoke graciously and importantly. Though he considered himself above most others, he would not dismiss any individual out of hand. He preferred to listen more than speak.
