Thelha Rath'nath

A third generation simulation World created by the power of Ormphlaus where Chosen Ones get transported into so that they can be further screened for their Fighting Spirit. The world serves as a training ground for Otherworlders so that they can develop their abilities and learn to collaborate with others to overcome dangers.

Locations
The World seemas divided into two Regions the outer region where the Chosen Ones get individually transported, and the inner region where they are trasnported together so that they can interect.

Safe Zone
Rock Mountains is a starting location for every Chosen One, where they are first transported to train. The area, as it's named, seems mostly composed of a desolate and rocky landscape It's populated by Magic Hounds that will attack any individual in the area, and possess the ability to adapt their strength to the individual's Level. The region possesses no other fauna or flora, and the only source of sustenance comes from Magic Hounds.

Once one Levels Up to Level 5 in the starting location, one can leave the starting area and join the rest of the other Chosen Ones in the Main Region.

Main Region
Not much is shown besides some flashbacks from Zanglu Xin. The Region seems to have woodland areas and seems to possess some Monsters that the Chosen Ones have to band together and defeat.

Once one Levels Up to Level 20 in the main region they will be transported to the world of Rathnia, but will not accomadate for the relationships formed before.
