A deceased and unnamed hero whose memories of a critical mission at Jade Gate Pass narrate the Burlap Sack series - slowly revealing his pivotal, forgotten role in the world.
Burlap Sack is the title given to an unnamed dead hero whose memories scatter across the landmarks of Jade Gate Pass and whose role the protagonist reconstructs piece by piece by visiting the same places he visited. He is not encountered alive; his presence in the game is exclusively memory-based, surfaced by the Young Master recalling fragments at each tied location.
The historical inspiration is the Angxi Army - Tang Dynasty soldiers who were cut off from the empire during the An Lushan Rebellion and continued holding the frontier without reinforcement, support, or return orders. Burlap Sack carries that historical weight in fictional form: a soldier on a mission too important to abandon and too distant to ever be relieved on. The quest series begins with A Brief Respite and closes with Roots Run Deep.
His journey across the desert is the arc the player reconstructs - dehydration, bandits, encounters with other figures who help or fail to help him, and a mission whose full content the Young Master only fully grasps in the closing memory of the series.
