Heart of the Brotherhood

"I leave my daughter now, knowing it is the only way to keep her safe -- the only way I can ever see her again. I left the Heart with her, for safe keeping, though she does not know it."

- Jeanne talking about the artifact in her diary.

The Heart of the Brotherhood was a First Civilization artifact that was used to activate the Prophecy Disk, taking the appearance of a heart-shaped medallion.

During the early 18th century, the medallion was in the possession of the Assassin Brotherhood on. The artifact was stolen by the African slave Jeanne, who had previously turned down an offer to join the Brotherhood. Jeanne was soon sold to the Louisianan noble Philippe Olivier de Grandpré, and took the artifact with her to New Orleans.

Jeanne became her owner's placée and sired a daughter, Aveline. After Philippe's new wife Madeleine de L'Isle informed Jeanne that François Mackandal was seen boarding a ship bound for Louisiana, Jeanne employed Madeleine's aid and left New Orleans to flee to Chichen Itza in Mexico. Jeanne left the Heart with her daughter, who did not realize what the artifact was.

Jeanne later found fragments of the Prophecy Disk during excavations of First Civilization ruins in Chichen Itza, but hid them so that they would not be found. Her daughter, who became an Assassin, journeyed to Chichen Itza twice and found both halves of the Prophecy Disk and took them back to New Orleans. Using the Heart to activate it, the device started playing a holographic recording of Eve's election as the leader of the human rebellion against the First Civilization.
