Sacha is a severed head with long topknot, thick black stitches closing up his neck-holes. Sacha was clearly once quite portly but now has leathery, dried skin and grey, receded gums. He has short fangs and claims to be constantly hungry for blood.

While much of his history remains unknown, he claims to be suffering from a curse that was unfairly laid upon him.

Sacha is usually found in the company of Wyan in the chambers beneath the Golden Tower.

He was found on the island of Mytilene and taken into the deep Sea of Silt where he was abandoned following the battle with Ul-Athra.
