Codex text

In the moment that it struck, the blade of the Grey Warden who killed Toth, Archdemon of Fire, shattered into three pieces. After the Battle of Hunter Fell, the Wardens carried their fallen brother to Weisshaupt for a hero's burial, but the broken pieces of his sword were left behind.

For years, the shards lay forgotten on the battlefield. Steel became etched with the corrupted blood of the dead god. They were eventually discovered by a Nevarran woman, searching among the bones for a sign of her lost son. She sold them to a blacksmith, not knowing what they truly were, for ten bits.

The smith, however, knew that he had purchased more than scrap metal, and fashioned the shards into three identical daggers: the Thorns of the Dead Gods. They left his hands and were scattered to the far corners of Thedas. But everywhere they went, the Thorns left misery and loss in their wake. The woman who unearthed them died soon after of plague. The smith fell into his forge. Each person who has held one of the Thorns, even briefly, has died an untimely death.

Trivia

The smith who created Thorn of the Dead Gods, may also have created the Hindsight as each item notes its creator fell into his own forge.
