Renefarious (レネフェリアス, Reneferiasu), also known as Renefarious XIII (レネフェリアス13世, Reneferiasu 13-sei) is a major character in Gensosuikoden Tsumugareshi Hyakunen no Toki. He is the Holy Emperor of the Holy Empire of Ionia.
Renefarious, like Lethe, was a Refiant, created some 300 years in the past and reinforced with magic power. He would be one of the sages who would help establish the Barrier, protecting a small area of land from the Terrus Firma and enabling him to establish the Holy Empire of Ionia in order to watch over it.
As long as he does not remove himself from proximity to the True Era Tree at the Palace of All Things, time does not flow for him as it does for others, leaving him immortal. Because of this, throughout the history of the empire, he has presented his reign as a dynasty.
By Holy Imperial year 100, he was Renefarious IV and married to Astrid, who would come to know of his immortality. By the time of Holy Imperial year 300, he is presented and known as Renefarious XIII, thirteenth in his line.
As the centuries passed, Renefarious would come to believe that the role of people in creating the Terrus Firma and the destruction of the Old World indicated that there could be no hope for peace and order outside of repressing the technology and curiosity of his people and using the Barrier to keep the Terrus Firma at bay indefinitely, despite its infrequent breaches.
Even following the destruction of the Terrus Firma by the hero, Renefarious would refuse to disperse the barrier, believing that the rapid accumulation of such land, prosperity and power would only provide the opportunity for the world to repeat its mistakes and bring it to the brink of destruction once more.
Fighting for the continued isolation and stagnation of the world, he would challenge the hero and his allies to battle. Defeated, although he realized that he had taken part in a battle against the 108 Stars much like that which devastated the Old World, he still believed in his actions and that the world would eventually be lost to despair.
