The Twilight Covenant was a peace treaty between the Angels and the Faceless that was signed in 0 YSD, bringing an end to the Elder Wars. When Sar-Elam ascended to Dragonhood, his first act after returning to Ashan was to gather the leaders of the warring factions, asking them to stop the fighting. In order to prevent a mutual genocide, and a disaster similar to the destruction of the Shantiri Empire, he used his new power and authority to impose a peace treaty on them. The two races swore a magical oath that would prevent them from using their magic to harm each other. The pact was enforced by powerful primordial magic that only the Dragon Gods themselves could break.
