Someshta

From A Wheel of Time Wiki

Someshta, also known as the Green Man, was the last of the Nym. He was set to guard the Eye of the World for the Dragon Reborn. It was common for Ogier Elders to consult with him.

He was killed when Rand al'Thor reached the Eye and was confronted by Balthamel and Aginor. Someshta killed Balthamel at the cost of his own life. In his final moments, a tree sprung up at the exact location he fell. His garden began falling to the Blight, but the Ogier Loial used his treesinging abilities to keep his tree alive.
