[Kanturu] is an area in the north-eastern part of the MU continent. It is here which a thriving race of civilization, which was by far the most advanced civilization than any other, once appeared. These people were known as the [Kantur People]. They had built a kingdom, now known as [Kanturu Relics], deep underground, inside the island. Through its development, and over many years of research and experiments trying to thrive inside their kingdom, the [Kantur People] were able to develop high-level skills in technology, biotechnology, and science. On top of this, they were able to incorporate the magical energies of [Arka] in order to developed very advanced systems. It is known to have been because of these systems, that the [Kantur People] were able to build an underwater city known as [Atlans]. The abundant resources of [Atlans] allowed the [Kantur People] to grow and develop beyond [Kanturu].

The [Kantur People] lived a life of satisfaction, mostly void to the problems occurring in the rest of the continent. During their time, they ultimately discovered ways to create various new life forms from the power of a [Jewel of Harmony], through their biotechnology skills. They discovered that the basis of creating a new life form was held within the power of a [Jewel of Harmony]. However, a pure [Jewel of Harmony] was near impossible to come by in nature. Therefore, the [Kantur People] spent many long years developing a method to purify unrefined [Gemstones]. Through its power, they began attempting to create mixed life forms by combining various species through the magical energies of [Arka], and by using the [Jewel of Harmony] as a medium. After mastering the art, [Dr. Jade], a superior biotechnology researcher of the [Kantur People], wanted to execute an experiment of creating the most intelligent life form known to exist.

Never-the-less, [Code ST-X813], also known as [Elpis], successfully demonstrated the intellectual capabilities that were beyond the expectations of researchers. Created with a goddess as a model, [Elpis] had feminist characteristics, causing [Dr. Jade] to think of her as her own daughter. [Elpis] learned a lot from the researchers, and absorbed the knowledge of their technology and of the [Kantur People]. Excited by the success of [Elpis], the researchers focused on creating another life form. This time, they wanted to create one with the most advanced combat abilities. Through their hard work, [Code ST-X814], also known as [Nightmare], was born. However, unexpectedly, [Nightmare] did not accept its existence, nor its creators, and instead took control over some of the other mixed life forms by starting a rebellion to escape from the control of the researchers.

Due to the unexpected behavior of [Nightmare], a battle between the [Kantur People] and mixed life forms began and spread into an internal war. During the long war, the [Kantur People] became impoverished, as they tried to regain their prior state, but [Nightmare's] strength and his recruited forces were too strong. It was this which caused the [Kantur People] to diminish. Eventually, their own doing would lead to the end of their civilization.

During [Year 1870 of Lugard], also known as year 1010, [Kundun] was resurrected. Consequently, the tranquil places of [Kanturu] and [Atlans] were attacked. Due to the internal wars of the [Kantur People], they had no forces reserved to help [Atlans] against the attacks by [Kundun], and it quickly fell into ruins. It was only after the destruction of [Atlans] that the [Kantur People] felt the urgency to fight together against [Kundun]. They tried to find ways to stop their forces, but by this time it was too late. Unable to block [Kundun], due to the lack of [Atlans'] resources, the prosperous civilization of [Kanturu] was inevitably destroyed and discolored in history. Despite it all, the [Refinery Tower] still stands in the [Kanturu Relics] and [Elpis] remains inside. However, [Nightmare] still roams around it, attacking anyone that tries to enter.
