Spider and 'Man' of Leng

The Satyr-like dwellers of Leng Plateau and a giant spider of the northen lands.
"They leaped as though they had hooves instead of feet, and seemed to wear a sort of wig or headpiece with small horns. Of other clothing they had none, but most of them were quite furry. Behind they had dwarfish tails, and when they glanced upward he saw the excessive width of their mouths. Then he knew what they were, and that they did not wear any wigs or headpieces after all.(...)
There were scenes of old wars, wherein Leng's almost-humans fought with the bloated purple spiders of the neighbouring vales."
