Aliases Heart of the Revel
Appears in Oathbringer

Ashertmarn is one of the Unmade, a mysterious group of odious spren on Roshar. Also known as the Heart of the Revel, his influence leads people to excessive indulgence,[1] which eventually leads to mindless excess, as is evidenced by members of the Cult of Moments that Shallan observes upon her entrance to the revel upon the Oathgate platform in Kholinar.[2]

Upon her inspection of the control building of the Oathgate there, Shallan found instead an inhumanly shaped heart.[2]

Ashertmarn was last heard by Shallan, who spoke to her.

Give in.

Join the revel.

Shallan, listen to me.[2]

After interacting with her, he fled.[2]


He is a dark mass that pulses and throbs. Black veins as thick as a man's leg run from it and meld with the ground nearby.[2]


Ashertmarn is a heart ... a heart that beats an irregular rhythm, bum-ba-ba-bum, instead of the common ba-bum of Shallan's own heart.[2]


Ashertmarn, the Heart of the Revel, is the final of the three great mindless Unmade. His gift to men is not prophecy or barrel focus, but a lust for indulgence. Indeed, the great debauchery recorded from the court of Bayala in 480 - which led to dynastic collapse - might be attributable to the influence of Ashertmarn.

–From Hessi's Mythica, page 203[3]


Brandon has confirmed that the Unmade are Splinters of Odium.[4] Odium splintered himself and created the Unmade to be his influence on Roshar. It is through the Unmade that Odium may be able to influence people in how they think or act.[5]
