Lore & Background
During her separation from Rudeus, she was temporarily under the protection of Ruijerd Supardia, effectively placing her under his guardianship while she navigated the dangers of the continent. Upon reuniting with Rudeus, Eris chose to leave her noble title behind in favor of a life with him. This decision marked her unofficial 'adoption' into the Grayrat family unit, where she eventually took his surname and assumed a central role in their household dynamics.
In Their Own Story
The heavy oak doors of the Boreas manor clicked shut behind her, sealing away the gilded cage of noble expectation. Eris adjusted the strap of her bag, feeling the weight of the sword at her hip rather than the silk of ceremonial robes. The wind carried the scent of rain and distant magic as she looked back once more, not with regret, but with a quiet resolve.
Reader's Guide
The narrative begins after the teleportation incident separates Rudeus and Eris during their academy days. Eris returns to her father's estate, where political machinations threaten her safety due to her mother's family history. Ruijerd Supardia takes on a protective role over Eris during this turbulent period, acting as a guardian while she waits for news of Rudeus. This temporary wardship is often cited by fans as the precursor to her permanent family shift. Upon their eventual reunion in later volumes, Eris decides to abandon her noble status to live with Rudeus. She integrates into his household, eventually marrying him and taking the Grayrat name, solidifying her place as a core member of his new family structure.
