The "War of the Jewels" is a significant conflict in J.R.R. Tolkien's legendarium, primarily detailed in "The Silmarillion." It revolves around the struggle for the Silmarils, three precious jewels created by the Elven smith Fëanor. These jewels contain the light of the Two Trees of Valinor and are highly coveted by various factions, leading to strife among the Elves, Men, and the dark lord Morgoth. The war is marked by betrayal, tragedy, and the quest for power, as factions vie for control over the Silmarils. Key events include the Kinslaying at Alqualondë and the battles of Beleriand, which ultimately shape the fate of the Elves and their world. The conflict highlights themes of greed, loyalty, and the consequences of ambition.
