Nasema Luminaris perished, his death devoid of significance.
From an utterly objective standpoint, His Grace the Duke of Luminaris indeed fell victim to a conspiracy — a plot, however, that neither the conspirators nor the conspired had ever intended to be lethal.
He was merely unfortunate to be in a position where anyone would have met their demise, and thus he died a meaningless death, taking with him the three-century legacy of the Luminaris family, all obliterated in an instant.
Perhaps it was precisely because his death was so devoid of meaning that our emperor, in her boundless mercy, did not annihilate the entire Luminaris lineage. After executing the Duke of Luminaris, she could not be bothered to deal with the rest.
With great benevolence, he left those bereft of their protector to the mercy of a pack of ravenous beasts.
