The magus Heserethia was a researcher and collector, one of the diaspora of arcane prodigies who frequently pass through Dis in search of pathways to planes of secrets and power. She took an interest in the plane of Absilia, with its historic conjunction of warring divine powers, but the Importers Guild of Dis barred her from traveling there lest she carry back some destructive angelic or titanic pest. She sought the aid of freebooters to sneak her through the embargo, and they did so, but a botched casting of the necessary planar travel spell landed her hundreds of years in the past instead of amid the flux of power she intended to study and harness. Once she understood what had happened, she turned her attention to spells of longevity (forward time-travel having stumped her), and has extended herself lich-like until such time as she can strike back at those who humiliated her.
