In 2E 576, Emperor Varen Aquilarios searched for the Amulet of Kings to become Dragonborn to legitimize his claim to the Ruby Throne. Keeping the Dragonfires lit until the Emperor's death. The Emperor was then soul - linked to the Amulet. In his rule of the Empire, it became tradition to take the Amulet of Kings and the newly crowned Emperor to the Temple of the One and light the Dragonfires. It was later found on Reman Cyrodiil's forehead when he was born. In 1E 2321, the Alessian Empire fell, and the Amulet was lost. The gem then contained her soul and her son, Belharza, and then his successors. Akatosh also created a Covenant to Alessia that required that her heirs stay true to the Dragon Bloodline, so that the Dragonfires could stay lit, and Tamriel be protected from Daedra. Others believe Akatosh drew blood from his heart to bless Saint Alessia, and gave her the Amulet of Kings as a reward for conquering Cyrodiil. The Ayleids then fused it in a red crystal and cut it in the shape of a diamond. When Akatosh and Trinimac tore out Lorkhan's heart and shot it across Nirn on an arrow via Auri-El's/Auriel's Bow (Akatosh), it is said that a droplet of blood fell into an Ayleid well. The Amulet is said to be a soul gem containing the soul of Alessia. The emperors had to be a blood relative of Saint Alessia, otherwise it would slip off. The Amulet of Kings is the amulet worn by the emperors of Tamriel.
