Erigor was the leader of the former Eisenwald Guild. Known as a "Shinigami," he exclusively took on assassination jobs and wielded a scythe as his weapon of choice.
Erigor instructed his guild members to secure Lullaby, a magical death flute, with the intention of killing all the Guild Masters during their meeting. Kageyama returned with the flute while Erigor commandeered a train, punishing Kageyama for alerting Flies about their plans. As Team Natsu approached Erigor, he left his guild to handle them while he prepared a Wind Wall to trap them at the train station. Just as he was about to cast it, Erza Scarlet challenged him, but Erigor managed to trap her before the fight could begin.
After resting, Erigor headed towards the Guild Masters but was intercepted by Natsu Dragneel riding Happy. The two engaged in a battle of fire versus wind, with Erigor casting his Storm Mail spell, which nullified all fire magic. However, Natsu's determination and increasing anger caused his flames to grow hotter, consuming oxygen and weakening Erigor's wind magic. When Happy advised Natsu to let Gray Fullbuster handle Erigor, Natsu instead went into a furious rage and defeated Erigor.
According to police reports, Erigor escaped arrest unlike his fellow guild members and has not been seen since.
