The Northern Elves
They are extraordinarily tall, and their skin is pale. Their hair is blonde or red and often long. Their features are bold. Their bodies are large and muscular. Their beards are often unkept but thick. They are the most reclusive of the elves and the least numerous, and their collection of lore is little, but they are strong. Most of their people live in Illum, a city made of ice and crystal, glazed with frost, twinkling in the sunlight like a beacon of fire.
They are sundered from a greater people called the Altresdolhn. The other part became the northern High Elves, or the Caládolhn. So the Altaic Elves look exactly as they once did, although they still have the tapered ears you see with all the other Yeqitari.
