Imperium City Orders

Another Pilot Story from the author of Heir de Winter:

When an abnormal surge of dungeons begins spawning in the continent of Oriar, it's up to Imperium City's Investigation Corps to collect information on such dungeons before dispatching Adventurers to close them. Upon Royal Decree, Imperium City Guild Employee Arian Rai is ordered to become an Investigator. Along with her partner, the mysterious Adventurer Blank, the duo embarks on their journey to investigate the mass dungeon outbreak. However, the more they uncover from these strange dungeons, the deeper into the rabbit hole they fall with secrets that might bring Oriar to its end.
