Lydia Beginsgate is an elf with long silver hair, light blue eyes, and pointed ears. She typically wears a revealing red corset top, matching bottoms, and laced high-heeled boots, though she donned white and pink gladiator armor during wartime. Ancestrally, she is linked to Ireena Litz de Olhyde, establishing a hereditary lineage across generations.
Her personality exhibits overtly perverse tendencies, specifically targeting younger girls with an obsession toward succubus virgins. This manifests as repeated sexual harassment of Ginny Fin de Salvan, including non-consensual groping during bathing. Despite this, Lydia demonstrates competitiveness and a capacity for regret, particularly regarding her role in slaughtering demons who refused to aid Demon Lord Varvatos. This guilt drove her to insist on accepting her fate and dissuade others from altering it; she destroyed Disaster Rogue’s immortality source to prevent him from changing history for his delusional goals.
Historically, Lydia fought alongside Varvatos to restore humanity’s control over the world. She was killed after being brainwashed by Mevilas, forcing Varvatos to execute her personally. Her spirit was subsequently bound to the sword Vald-Galgulus, which later came into Ard Meteor’s possession.
During time-travel events, Lydia’s spirit interacted directly with Ard. In these encounters, she continued harassing Ginny, prompting Ard to intervene physically. Though their initial confrontation ended in a stalemate, Lydia later confronted Disaster Rogue—Ard’s alternate-world counterpart—denouncing him as an "idiot" for attempting to manipulate fate. Her spirit form remained tied to the sword, enabling ongoing communication with Ard.
Lydia is a formidable warrior, skilled in aerial combat and swordsmanship, often depicted wielding her sword with high agility. Her abilities position her as a crucial figure in conflicts, blending martial prowess with tactical influence.
Key relationships define her narrative. She served as a close companion to Varvatos, whose reincarnation as Ard Meteor did not sever their connection; she acknowledged their bond while chastising his alternate self, Disaster Rogue. She is adoptive sisters with Slyphy Marheaven, though their dynamic involved friction, with Lydia openly criticizing Slyphy’s naivety regarding Ard’s role in her death. Her harassment of Ginny created tension with Ireena, who expressed disapproval of her ancestor’s behavior.
