Rubiera, sister to Kilian and Yurion, endures captivity under Baron Celdion, a nobleman orchestrating conquests across neighboring lands. When Kilian sacrifices himself to aid the protagonists’ escape from a slave ship, they pledge to return his pendant to Rubiera and Yurion—forging her link to their mission to dismantle the baron’s schemes. Her royal lineage, leveraged by Celdion to legitimize his political ambitions, positions her as both prisoner and strategic asset. Though her heritage and kinship drive the protagonists’ resolve, her personal history, relationships, and agency beyond catalyzing their quest remain unelaborated in existing records. No documented expansions of her character or appearances in other narratives exist.
