Vaults

Vaults are underground complexes, the vast majority of which were built during the Age of the Varn by the Grand Guilds.
Each vault had a specific purpose. Many were research facilities, designing new magical technologies. Others were bunkers, and others still were hidden arsenals. Many vaults were all of the above. It is unknown how many vaults exist in total. Adventurers still discover new ones to this day.
Vaults are dangerous places to explore. Most have powerful automated defenses that function to this day, while others have been breached and used as lairs by deadly monsters. However, they are prized for being treasure troves of lost technology and forgotten magical lore, and so there are always those willing to brave their ancient corridors.
AURA has specific regulations regarding adventurer interactions with the ancient dungeons. If an adventuring party obtains info on the location of a vault, and plan to visit it, they need not report this to AURA. Once they do visit it however, they must report its location to AURA as well as any mechana they obtained from there. Vaults are considered places of historic inheritance, and scholars and archeologists must be brought in to research more about their past.
