Death of Thingol

Thingol thought to place the Silmaril into the Necklace, and hired the Dwarves of Nogrod to do so. The Dwarven craftsmen also coveted the jewel and seeing that it was by their skill that the piece was made, saw no reason to give it up willingly. Thingol became enraged declaring that he was of the first Eldar to set off on The Great Journey and that they were guests in his realm. When he tried to take it from the Dwarves they slew him. This set off a chain of events leading to the destruction of Doriath and the scattering of its people. After Thingol's death Melian, who remained in Middle-earth by binding her spirit to that of her husband, chose to forsake her body and return to Aman as a Maia, removing the power which once protected it, leaving Doriath vulnerable to attack from without.
