Ada

In Mongolian tradition, a ada was a type of that soared in the sky, spreading illnesses and other misfortunes.

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 the 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.

The ada came to Sa'id ibn Hawqal last, after the shaman he hired to banish the first two failed. The ada looked like a twisted version of Bagadan himself. The ada promised its breath would bring Sa'id fever and a painful death. Desperate, Sa'id made his way through the city and, by chance, found a synagogue. At first he was surprised, and prepared to move on. However, he reasoned that, given the close relationship between Judaism and Islam, he might find comfort here, and went inside, which proved the correct decision: the Rabbi Yen Hui finally banished the demons.
