Dungeon from the Void Books in Order

A young dungeon core emerges from the void into a secluded mountain range in Midgard. Possessing an exceptionally dangerous element, he begins building a new existence in a world where cultivators enter dungeons seeking power and survival.

As conflict approaches, Fenrir faces a more immediate problem emerging from beneath his dungeon. His growth has carried the new Dungeon City of Wolfdenn forward, but an unexpected intrusion threatens to disrupt their shared progress.

Fenrir studies a party of mercenaries making its way through his growing dungeon. Meanwhile, a half-elf mercenary adjusts to becoming a city lord, and neighboring nations prepare for a conflict that could affect them both.

Fenrir and his dungeon continue gaining strength as their newly established nation grows alongside them. Encounters with unfamiliar races bring fresh opportunities and threats, raising questions about how long their relative peace can continue.
