Olgoi-Khorkhoi (Mongolian Death Worm)

The sources consulted do not supply an origin myth, genealogical account, or placement within Mongolian cosmology for the Olgoi-Khorkhoi. In the available material the creature appears as a named folkloric or cryptozoological entity associated with the Gobi sands rather than as part of a recorded creation or spirit-account; it is presented as a mysterious desert-dweller without an attested indigenous origin narrative in these references.

The cited references describe Olgoi-Khorkhoi only as a "worm" or "wormlike" creature that lives beneath the sands of the Gobi Desert. No reliable details concerning size, color, anatomical features, or other morphological specifics are provided in the available material; beyond the broad characterization as a subterranean worm the sources are silent on physical description.

The available sources characterize the creature as "deadly," implying danger to humans, but they do not document specific abilities, modes of attack, or supernatural powers. The brief references do not record whether it kills via venom, physical attack, electrical discharge, spitting, or any other means; no behavioral mechanics or demonstrated feats are provided in the cited material.
