Mal'akh is revealed to be a Freemason with tattoos covering almost his entire body. He infiltrated the organization in order to obtain an ancient source of power, which he believes Langdon can unlock for him in return for Peter Solomon's life. Several chapters also delve into Mal'akh's history with Peter Solomon: many years earlier, Peter bequeathed a large sum of inheritance money to his rebellious son, Zachary, who then fled the Solomon household and led a reckless life in Europe until he was arrested and imprisoned in Turkey for smuggling drugs. Peter flew to Turkey but decided to have Zachary extradited in a week's time instead of getting him released immediately in order to teach him a lesson. Zachary was apparently murdered by his cellmate who got his hands on Zachary's fortune and fled to the island of Syros in Greece to lead a luxurious life under the name Andros Dareios. Dareios, however, soon grew tired of his life. Apparently having spoken with Zachary about Solomon's life as a Mason, Dareios broke into Solomon's home to find the pyramid, but accidentally killed Peter's mother Isabel and was in turn shot and left to fall into a frozen river by a vengeful Solomon. Surviving the fall, Dareios nursed himself back to health, covered his scars and eventually his entire body with tattoos and set off on a mission to infiltrate the Freemasons and gain access to their secrets, adopting the name Mal'akh.
