The Miller family initially obtained the rights to develop Sinless City through political means, but the criticism from other federation members began when they failed to gain control of Gold-digging Dock even after such a long period of time.
Now, nobody believes that Stan Miller, who couldn't even protect his own life, would be capable of taking control of Sinless City.
After the re-vote took place in the congress, the main Miller family from Dragon City couldn't stand the pressure and gave up their exclusive business rights to Sinless City.
However, after a lively debate, no one was able to claim those rights.
So, they simply opened it to all interested parties.
The moment this decree was issued, the big financial groups from the rich ore layer, smelling profit like bloodhounds, all swarmed to Sinless City.
Now, Sinless City seems like a no-man's land, and everyone wants a piece of the pie.
