Sinstone golems are generated through the unresolved sins of those souls who failed their redemption and were condemned to the Maw and can grow more powerful if exposed to anima. The Curator once knew the contents and locations of every sinstone in Revendreth dating back to the foundation of the realm, essentially having all the Sinstone Archives memorized, but her time in the Maw has altered her memory temporarily.

Sinstones can also be abused by being bound to their soul, as well as corrupting a bound sinstone with more anima and through the sins of others, which can lead to instability and self destruction of the soul, which can lead souls to be condemned to the Maw. Sinstones of powerful venthyr tend to go 'missing', stolen for fear of their sinstone being used against them, including compeling souls into service and submission. Souls that become venthyr are usually kept within the Sinstone Archive, maintained by Archivist Fane, in both the Halls of Atonement and Archivam within the Catacombs Ward. Traditionally, the stoneborn Temel is in charge of publicly announcing the true name and sins of every single soul that has ever passed through the Halls of Atonement. Sinstones bear the true name and sins of a venthyr, as souls are given a new name if they become a venthyr, requiring both being redeemed during the Ritual of Judgment and chosen to be sired by another venthyr.

The venthyr Maneo is in charge of assigning sinstones to souls, where each soul is forced to chisel their sins into their stone, handed to them by a dredger. Throughout Revendreth one sees sinstones, which represent the souls that have left Revendreth cleansed of sin. Sinstones are gravestone-like manifestations of a given soul's accumulated burdens of their life, generated and assigned upon arrival into Revendreth at Pridefall Hamlet.
