Tishana

Shaper Tishana, also known as the Voice of Thunder, is a wizened shaman of the River Heralds on Ixalan.

History
Tishana is the eldest and most powerful of the Nine Shapers. She claims leadership over every band. Though her magically amplified voice can drown a pirate ship or scatter a vampire band with a single word, her own people find her a warm and kind elder.

Tishana temporarily joined up with Huatli in their race to prevent Kumena from gaining control over the Immortal Sun. After saving Kumena, when he was thrown out the Tower of Trumph, Tishana was one of many who joined the scramble for control of the powerful artifact.
