Glenwood (グリンウッド Gurin'uddo?) is the name of the large continent in which the events of Tales of Zestiria take place, while the planet itself is unnamed in the game. Likewise, the existence of other landmasses is unknown due to the limited technology of the medieval setting. In Tales of Berseria, which takes place around 1,000 years prior to Tales of Zestiria on the same planet, albeit with a vastly different continental formation, the world is given the name Desolation.
Glenwood is divided into two main countries: the Kingdom of Hyland and the Empire of Rolance. The continent itself is mostly explorable, with fairly populated cities scattered throughout and several ruins sprawled on the surface and within the depths of the landmass. The eastern half of the continent is far larger than the western half, which it connects to via a small land bridge, as well as the Great Camelot Bridge, which was built by Rolance. Hyland's territory tends to be mountainous, while Rolance's territory is marked by open fields, vast plains, and thick forests. The territories to the north beyond the great gate at Zaphgott Moor are not visitable, and it is said that a third country is located there.
In Tales of Zestiria the X, in the episode "The Ideal World", the "land to the north" covered in snow is shown via Symonne's illusions, which is said to be a place where no humans live and even beasts barely survive. Great amounts of malevolence are located there, where Heldalf has presumably made his headquarters as he feeds on the malevolence that is there. It is likely located in the third country's territories mentioned in the game and presumable based on the geography of Tales of Berseria, but likely nothing is heard from it due to it being succumbed and destroyed by malevolence.
