Damnation
Damnation is a place in the cosmology and religion of Roshar in Brandon Sanderson's The Stormlight Archive. In Vorin belief it is a realm of torment, and it has a literal counterpart in the history of the Heralds and the Desolations.
In Vorin religion
In Vorinism, Damnation is conceived as a place of punishment, contrasted with the paradise of the Tranquiline Halls from which humanity is said to have been cast out. Vorin teaching frames existence as a struggle to prove oneself worthy of helping reclaim the Tranquiline Halls rather than being consigned to Damnation.
The Heralds' torment
Damnation has a more concrete meaning in the history of the Desolations. When a Herald died in battle against Odium's forces, their soul was drawn to a place of torture, identified with Damnation, where Odium tormented them. So long as the Heralds endured this agony without breaking, the next Desolation was held back. The Heralds eventually abandoned this burden, leaving only Talenel to bear it, for thousands of years, alone.
The world Braize
In the wider Cosmere, the torment associated with Damnation is connected to another world in the Rosharan system, sometimes identified with the planet Braize, where Odium and the spirits of the enemy were confined between Desolations. The mythic and the literal meanings of Damnation are thus closely intertwined in Rosharan history.
