Sorqan Shira first appears in The Secret History of the Mongols, when Temujin manages to escape from the Taichiud captivity in 1177.
Passing by Sorgan-Shira noticed a young man hiding in a river backwater, but reassured him, promising not to give out.
Several times, Sorgan Shira persuaded the pursuers to continue the search for the fugitive elsewhere.
[1] They removed and burned the block into which Temujin had been chained, and Sorgan himself hid him in a pile of sheep's wool, instructing his daughter Qa'daan to look after the fugitive.
Submitting to Genghis Khan, Sorgan Shira and his sons became generals for Genghis, his son Chilaun personally killed Taichiud chief Targutai-Kiriltukh.
