Leng (or Plateau of Leng) is a fictional cold arid
plateau in the
Cthulhu Mythos, whose location seems to vary entirely from story to story. The Plateau of Tsang, referenced by
H.P. Lovecraft and other authors, is probably a region of Leng.The mad
Arab Abdul Alhazred describes it as a place where different realities converge, which might explain why its precise location cannot be pinned down.
