Vadis Free City

Vadis Free City (ヴァディス自由都市) is a small independent city in the New World.

Background
The city was among the small towns that the Baharuth Empire and the Re-Estize Kingdom jointly constructed to keep the undead-prone Katze Plains area at bay. Cities like these help adventurers and knights of the Empire to clear up the undead.

Mass for the Dead Arc
In the game, this city appears when Leinas Rockbruise guides the protagonist and their team, composed of Soi and Slimeko, to assist in undead subjugation in the Katze Plains.

Layout
A small city located on the highway on the north side of the Katze Plains southeast of E-Rantel. Though it's officially called a city, its population is technically too small. The area around the city is blanketed in fog due to the Katze Plains. The city is noted to have tall walls, thick iron doors like a fortress.

Trivia

 * The age of the city's establishment is unknown but since the Kingdom and Empire have a stake, it seems that the city was most likely founded since about 200 years ago, when the two countries split from the same nation.
 * Undead elimination in the Empire was treated as government work, and thus one could head to the Empire's Administrative office to collect payment for their undead subjugation.
 * In the game, the city is never actually seen, though the characters and players are directed to it off scene. Though it's mentioned by Slimeko to have a symbol of the Four Great Gods and their subordinates.
