Seven Hidden Mines

Seven Hidden Mines was a location in YGGDRASIL that contained deposits of prismatic ores.

Background
The clan Nine's Own Goal once possessed a monopoly on the entirety of the Seven Hidden Mines. They discovered that the mines contained a wealth of celestial uranium. After mining the ore until the mines were depleted and later stockpiling it, the clan was came across an unexpected tun of events. Apparently the celestial uranium had transformed into Caloric Stone.

The Seven Hidden Mines were later taken by a rival guild. Through the use of Ouroboros, a World Item, they banished Nine's Own Goal from the world in which the mine were situated. Each of the seven mines then came under the control of several independent guilds.
