Rivira (リヴィラ) is a town made by adventurers located on the 18th Floor of the dungeon.
Rivira is operated by adventurers. Item trades are common, and there is also an inn and bar located there. The inn and bar are overpriced but adventurers still use them. Rivira has been rebuilt over 300 times after monster attacks. The Guild isn't affiliated with Rivira and items banned on the surface are common.
Rivira is named after the female adventurer Rivira Santilini (リヴィラ・サンティリーニ) who founded the city.
