Kingdom of Dawn, Thorn Town.
The deserted little town situated at the foot of Cage Mountain had turned into a bustling and lively location.
Aside from being an "Outpost" and headquarters for Cage Mountain, the other reason was that it housed the Aerial Knights Academy frontline training camp.
To meet the enormous expenses of the Aerial Knights, the engineering team constructed many wide and reinforced concrete roads that connected the main road from north to south which led all the way to the far north in the Kingdom of Dawn. The large import and export of resources naturally attracted the attention of merchants from the Kingdom of Dawn, and having lost their trade routes to Kingdom of Wolfheart and Everwinter, Graycastle became their largest hope of making money. From supplying services that contracted them for the entire project to supplying beverages, there were all kinds of merchants.
