The Tishooo, also known as the Old Man, is the Falling Man manifested as wind, specifically, the wind from Nekrien. This means that in the Southern Wastes, he's the east wind, while in the Riverland, he's the south wind. He is also related to the Witch King of Nekrien. In Kothifir he is much-loved, as he protects them from the Shuu and Ahack winds from across the Barrier, as well as protecting them from being buried in sand.
