History
Sometime in the past, the god Mithras became separated into the aspects of Verethragna, who embodied his aspect as a war god, and Mithras, god of light and order.

In the modern era, Verethragna battled against Melqart. In the Light Novel, this was witnessed by Lucretia Zola early in the story. According to Verethragna, Melqart was injured during their last confrontation and his wounds had still not healed. Later, Verethragna was defeated by Godou Kusanagi.

In the light novel version, Verethragna lost his memory in the battle, with most of his Authorities being scattered around the island. He befriended Godou, and (at the request of him) used Prometheus' Grimoire to defeat one of his own avatars, restoring some of his power. Later, Godou Kusanagi stole the power of the White Stallion with the Prometheus' Grimoire. He was forgiven by Verethragna for entertaining him earlier in the story but warned that the next time he would be punished.
