Nur-Ab-Sal is a character from Indiana Jones and the Fate of Atlantis (1992).
Nur-Ab-Sal was high-priest and king of Atlantis who aided the Atlantean people in surviving the great flood. Nur-Ab-Sal accomplished this via an orichalcum, "God Machine" which mutated the Atlanteans into having similar biology to a species of advanced aliens that had visited the nation.
Nur-Ab-Sal went on to experiment with this technology on slaves and criminals only to start an uprising of mutated Atlanteans which killed him. Before his death, Nur-Ab-Sal created a necklace to hold his spirit within so that he could one day return. This necklace came to be allocated in Iceland by the early 20th century.
In 1929, the necklace was recovered in Iceland by the Jastro Expedition of archaeologists Dr. Jastro, Indiana Jones and Sophia Hapgood. Sophia would keep the necklace, causing the spirit of Nur-Ab-Sal to speak with her and lead her closer to finding the ruins of Atlantis. In 1939, she and Jones found Atlantis only for Nur-Ab-Sal's spirit to possess Sophia to use his ancient machines and turn him into a god through Sophia's body. Jones foiled these schemes however by throwing the necklace into lava, seemingly destroying it and Nur-Ab-Sal.
