This is one of the most analyzed mysteries in the entire Wheel of Time series. Since The Fires of Heaven was first published in late 1993, the identity of Asmodean's killer has been fiercely debated among fans. Robert Jordan has said that the identity of the killer was not meant as a deliberate major mystery, but he was so amused by the commotion over it that he refused to answer who was responsible. He hinted that A Memory of Light would resolve the mystery, or if it didn't he would slip it into the paperback release of the final volume in some fashion. Following Jordan's passing, Brandon Sanderson has confirmed that the final book (now the final three books) will answer the mystery and was one of the first things he looked up when he had access to Jordan's notes.
