Kolcin

In Mongolian tradition, a kolcin was a type of ghost demon that had a horrifying appearance.

Kolcin in "Curse of the Three Demons"
Bagadan summoned a kolcin, an eliye, and an ada to curse the Arab merchant Sa'id ibn Hawqal. When Sa'id returned to the caravanserai where he was staying, he began praying, but was immediately plagued by thea kolcin. Even though Sa'id tried to pray it away, order it away, and even attack it with a knife, the kolcin remained. After taunting Sa'id that it was tasked only with giving the first hint of its master's wrath, the kolcin sank through floor and vanished.
