Legend has it that was massive explosion in the heart of the desert that rocked all the neighbouring lands. It is said that it was the Hand of God himself that crashed down on the wasteland. Years later so a few people mustered the courage to visit the site of the devastation, they were surprised to find a massive crater. When stepped foot into the crater, a sort of radiation was felt, one that made sick people feel as though they were cured of their illness. As word spread, people came to visit "The Crater of Healing" and
after some time an artificial source of water was created to support crops that the locals could consume, thus the crater became a trading town. Which further developed into a well defended stronghold over time.
However now, the times have changed and some people with power do not want to mere become a part of that society but rather own the whole region themselves. The stronghold must defend well against the invading armies of multiple lords around the region. And to make a statement that the operations within the "Stronghold of the Healing Crater" have not been thwarted due to such attacks, an ample amount of gold must be raised as well.
