Stagnant
Whether you were placed in the mines, the steel mills, or working with the machines, life in Hadestown was mostly the same. With no sense of time you worked until the rare break was offered, were paid your wages, and then it was right back to the daily grind. Sometimes you'd visit the Queen's bar, but no one talked about that out loud.
Once in a while, some brave, foolish soul would try to shake things up, calling for rebellion. When people talked like that, if you were smart you kept your head low, and if you were smarter, you'd inform Mr. Hades.
He'd give you praise, and you'd drink it up like you were starving, and then it was back to work, to endless monotony. You couldn't tell your peers apart from yourself, and the more you lost concept of yourself. Soon you were a machine made of flesh.
Like a broken clock, Hadestown was stagnant, static. It never changed, and never would, and of all of Hades' promises, that one rang most true.
