Liet Rochben

Liet Rochben is a legendary chronomancer, and although he is most well known for his role in slaying the many demons created by the Eidols, he didn't actually kill any of them.

Liet came to Asnea through a portal created by Skylen Curiousitas, making him one of the few interdimensional travelers.

When he first met Skye, she saved his life by bringing him into the universe of Ikinokori using the mirrored portal. Soon after, she implanted an experimental device that required blood to operate in his arm which allowed him to manipulate time to some extent and also transport to a previously set location. After attempting an assassination on the current ruler of Asnea, Oscar, Liet was forced to use this device to retreat to safety, which damaged the device and altered his genes, allowing him to use these abilities freely. Upon a second attempt, the assassination was successful, however Skye and Liet were forced to retreat through the mirrored portal, destroying it in the process.

Years later, Liet and Skye returned to Asnea, although Skye was rendered unable to speak from her clash with Oscar. Liet traveled with Skye to see what had become of Asnea during their time away. They ran into Bastien, a homunculus turned demon, who murdered Gage and Skye. On his deathbed, Gage gifted Liet his right eye, which was a fabled treasure known as Dargus Oxum. This eye was actually an eyeball that had been stolen from the dragon Gaius by Colbrandt in his attempt to ascend to godhood centuries earlier.

With the power of the dragon's eye, Liet travelled to Asnea and defeated the new ruler, Balthazar the Wicked. Although Liet had defeated the demon Balthazar, he was unable to ensure that Balthazar would not regenerate. So Liet put his heart into stasis until he could find a way to permanently put an end to Balthazar.

After the events of Asnea, Liet began to search for a way to kill the demons that had been created by the dragons. Eventually he met with Colbrandt, who had managed to ascend to "godhood", meaning he had achieved his goal of becoming a dragon. Brand gave Liet his blessing, allowing him to further hone his ability to manipulate time and space. In exchange for this gift, Liet agreed to give Brand his soul upon death, allowing him to be turned into a demon. This alleviated the stress that his powers were putting on his body due to the amount of blood required to maintain the stasis he was using on the hearts. Liet then proceeded to hunt down the demons that were terrorizing Asnea, and upon defeat would put their hearts into stasis, which prevented their regeneration while he searched for a way to defeat them.

Eventually, due to the limitations of his mortal body, Liet died of old age. Brand comforted Liet during his final moments, ensuring he could transform him into a demon as quickly as possible. Upon Liet's death, all of the demons he had previously defeated were able to regenerate due to the stasis he was maintaining being removed.

Liet's transformation didn't quite go as planned, due to his incredible willpower. Most demons were filled with resentment and hatred which made them easy to manipulate, but Liet did not suffer from those negative traits. As a demon, Brand was barely able to control Liet. Liet was forced to obey Brand's commands, but was able to twist the orders to fit his own goals. Ultimately, Brand gave two ultimatums that Liet had to follow: Liet was not allowed to kill himself, and he was not allowed to kill Brand.

A few years after these events, Steiner, who had taken over control of Asnea and transformed it into a futuristic eutopia, decided that she didn't want any other dragons on Asnea. Steiner created a demon, Sabine, and gave her the means to destroy other demons. Brand ordered Liet to kill Sabine, but because she was a demon Liet had no way to defeat her. Liet decided to use his time manipulation to trace her bloodline back as far as he could and kill her great ancestors, but discovered that she was actually one of his descendants, and in order to kill her he would have to kill himself, as Brand refused to tell Liet how to defeat a demon.

Eventually Sabine confronted Liet, which led to his death since the only way for him to defeat her had been restricted by Brand. However, before Sabine delivered the final blow, Liet used his time manipulation to travel forward in time, allowing him to delay his death indefinitely.
