Oliver Schtrom, born Oliveira von Schtradius, ascended as a Bluesphere Empire noble leading a ducal house with royal lineage. Celebrated for advocating commoners' welfare through progressive reforms, his popularity sparked aristocratic resentment. His marriage to Aria, then expecting their child, enhanced his stature as a benevolent leader. Surging migrations to his lands provoked rivals to falsely accuse him of human trafficking and torch his estate, murdering Aria and their unborn heir. Shattered by loss, he unleashed apocalyptic magic that ravaged his domain, morphing him into a rare lucid demonoid. Renamed Oliver Schtrom, he propagated demonoid outbreaks across kingdoms, corrupting figures like Kurt von Ritzburg into agents of chaos. Disguised as an Earlshide instructor with a concealing eye mask, he clashed with Shin Wolford—a prodigy he initially deemed a threat. Speculation arose that Shin, spared from the estate massacre by Aria’s covert actions, might be his surviving son. This revelation撕裂ed Schtrom’s psyche, opposing paternal hope against vengeful fury. Seizing the Bluesphere Empire through noble extermination and mass demonoid conversion, he found hollow victory. Adrift without purpose, he pursued conflict for stimulation, battling the Kingdom of Sweed after prior invasions crumbled. Tormented by dual impulses—embracing demonic power or reclaiming humanity—he remained unresolved. His legacy lingered through Silver, a child tied to Schtrom and Miria, adopted by Shin and Sizilien under ambiguous circumstances. Schtrom’s arc spiraled from idealism to nihilism, juxtaposing past compassion against present brutality to mirror vengeance’s corrosive cycle and identity’s fragility in a violence-plagued world.
