The story was quite bizarre, but it perfectly explained the game's elements.
A Steel Dwarf had snuck into the town and stolen the keys to the town warehouse. There had been numerous raids since, but he had not yet been found.
The Dwarves were divided into three major tribes – Bronze, Wildhammer and Iron. However, they all looked quite similar.
The three tribes had a very long-standing hatred, but they were quite equal in strength, so none of them would never truly dominate the continent.
This was because they all had some fatal personality trait. The Bronze Dwarves were too straightforward, the Wildhammer Dwarves were too independent and the Iron Dwarves were too cynical.
The Bronze Tribe lacked strategy, the Wildhammer Tribe lacked diplomatic cooperation and the Iron Tribe lacked decisiveness. Because of this, they could never work together.
Regardless, when Lu Li heard that the key had been stolen, he wasn't surprised at all.
