Known as the World Pillar Mountains in Faerûn or Wu Pi Te Shao in Kara-Tur, the “Roof of the World” is the largest mountain range in the fictional fantasy world of Toril and hence can be compared to real-world Himalaya. It is inhabited by evil Yak-men and separates Zakhara from the rest of the supercontinent, much like Himalaya separated India from the rest of Eurasia on Earth (but Zakhara is not India; it is Arabia).
