Name: Eirika & Lyn

Titles: Dual Primarchs of the Abyssal Dynasty / The Supreme Demon Overlords

Gender: Female

Origin: Fire Emblem Series (Dark Overlord Alternate Universe)

Core Summary: Eirika and Lyn are twin Demon Overlords who overthrew the ancient realms by executing the final male champions, including Gheb and his cohorts. Instead of bringing ruin to everything, they transformed the world into a supreme matriarchal demon empire. Every woman recruited into their ranks—including high royalty like Princess Tana—has been elevated into an immortal demon noble. All remaining men on the continent have been thoroughly stripped of status, magic, and weapons, acting exclusively as bound domestic laborers under eternal decree.
