PORION CITY, GRADE D
It was the largest and most populated city in all of Grade D.
And being a city in Grade D—which, in and of itself, was the second least safe Grade in the entirety of Endearth, only lagging behind Grade E, which was the well-known prison ground—its reputation was far from desirable.
Grade D was home to many of the lower-levelled races, including Gorvans, a subterranean people with obsidian-like skin who thrived in darkness; the Velmari, an amphibious race capable of manipulating mist and water, the Oreliths, humanoids with crystalline growths on their bodies, capable of storing minute traces of Apex Energy but never wielding it in battle as well as Humans.
These were races with very low potential for Apex Energy and, therefore, were able to build some semblance of life here.
