Sheytusung (lit. Riverlight) is a katana forged by master smiths in Pahmey.

Its first owner was Salai of Oshy. Salai relied on the blade extensively in a war between Qaelin and Ilar; twenty years later, he used Sheytusung to slay several invading Timandrians. Upon Salai's death, Sheytusung passed to Koyee. In her service, the sword saw many battles: in Pahmey, Yintao, and Cabera Mountains. Sheytusung later passed to Madori and was renamed Min Tey (lit. Waterglow).

Sheytusung is 40 inches long, and its blade is formed of folded, mottled steel. Its hilt is wrapped in dark silk.
