High Priest Not to Be Described

The High Priest Not to Be Described (Elder Hierophant, Tcho-Tcho Lama of Leng) is a fictional character in H. P. Lovecraft's Dream Cycle. He first appeared in the Lovecraft short story "Celephaïs" (1920).

The High Priest Not to Be Described is the sole occupant of a remote and ancient monastery on the Plateau of Leng in the Dreamlands. It serves the Outer Gods. It's possible that it may be the King in Yellow, Hastur. Another oft-conjectured possibility is that it is the Crawling Chaos, Nyarlathotep.

The monastery where he dwells has a confusing tangle of lightless corridors with disturbing frescoes that chronicle Leng's bloodcurdling history. Deep in the bowels of the monastery, inside a frightening domed room, the High Priest Not to Be Described sits on a throne of gold atop a stone dais in pitch-black darkness. Five steps down from the dais is a row of six blood-stained stone altars surrounding a yawning well that is rumored to connect with the Vaults of Zin in the underworld.

In Lovecraft's novella The Dream-Quest of Unknown Kadath (1926), Randolph Carter has a fateful encounter with the High Priest Not to Be Described. The only description of the High Priest is given in this passage:

...and there... sat a lumpish figure robed in yellow silk with red and having a yellow silken mask over its face. To this being the slant-eyed man made certain signs with his hands, and the lurker in the dark replied by raising a disgustingly carven flute of ivory in silk covered paws and blowing certain loathesome sounds from beneath its flowing silken mask.
