Lore & Background
Klaus Fauresia was a man consumed by status and magical ambition. While outwardly presenting as a respectable noble, he secretly collaborated with factions interested in opening pathways for demonic forces into the human world. This involvement required significant resources and sacrifices, which he attempted to extract from his own household, including his daughter Eris. His relationship with Eris was fraught with neglect and cruelty. Unlike her mother Ariel, who showed some capacity for affection, Klaus viewed Eris as a tool or an obstacle to be managed. His obsession with the teleportation gate project created a volatile environment that eventually drew Rudeus into their lives during his quest to rescue Eris from captivity. The Fauresia clan's downfall began when their secret operations were exposed. Klaus refused to abandon his plans even when confronted by the threat they posed to the continent. His refusal to step down and protect his daughter ultimately sealed his fate, as Rudeus was forced to intervene to stop the magical catastrophe.
In Their Own Story
The manor hall fell silent save for the crackling of magic in the air. Klaus stood before the glowing portal, his back turned to the intruder who had shattered the door. He did not turn immediately; he knew what came next. The young mage behind him held a staff that hummed with lethal intent. Klaus looked at his daughter, trapped and weeping near the gate's edge, then slowly faced his enemy. There was no plea for mercy in his eyes, only the cold calculation of a man who believed power justified everything. In that final second, he realized his ambition had cost him more than just his life.
