Mesica might have been only a small and poor town in the US, there was one significant figure there, Edward.
Although he wasn't that significant, his family, the Bohr family, were a member of the famous Black Hand Gang in the US.
In reality, Edward no longer counted as a member of the Bohr family, but other people didn't know that. The reason why Mesica Town had stayed the way it was was greatly due to Edward.
Edward used his family's name to earn money in the town, but since he never stepped out of bounds, he'd stayed on good terms with the local government. At times, they would even work together.
The largest private manor in town alsi belonged to Edward. He had around 40 to 50 men working for him. Sometimes, he would even commit some robberies at nearby towns, but what was clever about him was that he never touched the government's bottom line.
