Tirasweel

Tirasweel (ティラスイール) is the northeastern continent that serves as the setting for.

Background
Tirasweel consists of seven countries: Pholthia, Menarth, Chanom, Ambisch, Udor, Oldos, Phenthe and Ghidona. The continent is surrounded by the mountain range Great Serpent's Backbone in the south and the enormous chasm Gagharv to the west, essentially isolating the land from the outside world. Of course, people aiming for unexplored worlds decided to cross the seas, only to discover they did not yet possess the technology to endure voyages that long and found themselves forced to return to the Silent Sea (沈黙の海).
