Qu Yuan's "Nine Songs" Scroll

Origin
"Nine Songs" is an ancient set of Chinese poems. Despite the name, the scroll actually contains eleven poems. Nine are meant to address cloud gods, while two are to address legendary heroes. The songs detail how to properly address and beseech the cloud gods for rain.

Usage
The scroll must be sung, as the inscriptions on the scroll were meant as a choral chant. If read properly, the skies will become cloudy and it will rain. Chanted improperly, a bolt of lightning will strike the immediate area of the user.

Collection
Collected by the Warehouse 7 agents during the Mongolian Empire.
