The place

What it is

The vault is a compact maze of counting halls, devotional alcoves, and sealed chambers cut into a low shelf of stone.

Atmosphere

Cold air carries the smell of dust, lamp oil, and old coins.

The threat

A young cave drake, drawn by the scent of old coin, has made the deepest chamber its nest.

History

The vault was built by the merchants of a distant, dry upland homeland to keep their coin and trade records safe through a long border war.

  2. 2A kobold band has taken to trading stolen copper for food, but none will go near the lower halls.
  3. 3A cave drake is said to sleep on a bed of gold, though the last person who claimed to see it ran away empty-handed.
  4. 4One of the old merchant ledgers proves that a family fortune was never properly claimed.
