In the Wild Hammer Kingdom, there was a saying:
The higher the temperature you bring home, the more affectionate your wife will be.
The further from the earth's surface one works, the closer to the earth's mantle they are, and thus, the higher the temperature.
This high-pressure, high-temperature environment bred many rare minerals, offering the Wild Hammer Kingdom's miners high-paying jobs.
If one were to work about fifty meters underground, they would only spend roughly fifteen minutes commuting each day.
For every additional fifty meters drop in the workplace, the commute time would increase by fifteen minutes.
Once the worksite was below five hundred meters in depth, the daily commute time doubled to a staggering six hours, forcing miners to overnight underground for over two weeks without seeing the sky or the sun.
The inflation of commuting time was a result of the required safety checks during each entry and exit.
