The Seine curse.

The Seine is rumored to be an  cursed object because all who come in contact die mysteriously and suddenly.

The supposed first victim is the author Larite and the Ayada he followed. Since it was first written, the Seine has disappeared and reappeared. The Seine has also never been fully translated, according to notes left by Sarphira, there are two more sections entitled the Wae and Atia. She died before finishing translation and The Seine was stolen shortly after.
