After confirming that things were in order, they went to the temple of the god of steam next. They went there to retrieve any letter that Tesla had sent to them.
The retrieval process took some time because his letters had been sent to Ivory Town. The letters had to be sent to Reinfield City again. For that, he had to pay some money.
There were other letters from other people. But he wasn't interested in them enough to bother to pay for them to be sent to him directly.
He could only arrange for the letters to be sent by train to Reinfield City. This would take some days and might even lead to some misplaced letters, but it was cheap.
After taking his letters, he returned home in the inner city. This is where rich merchants and other upper-class people live.
Reinfield City is about four times the size of Ivory Town. But there are ten times more people in Reinfield City than in Ivory Town. So Reinfield has a higher population density.
