Ganlas is the common name for the largest mountain in all of existence. The mountain itself stretches to the sky and beyond, the peak and upper reaches are consistently obscured by cloud cover. There is a folk tale about an unnamed adventurer that reached the peak and discovered that Ganlas has pierced the veil of the world, opening a portal to other worlds, whether the tale is grounded in fact or fiction no one knows.
At the base of the mountain lie a maze of valleys and "hills" that intertwine. It is rare for any towns or villages to set up in these lush valleys, mostly due to the vast monstrosities that roam between the hills. These monsters are typically highly violent.
