Lex did not interrupt, though he had many questions. It was obvious that those who inhabited this place did not travel by walking the distance manually, and used some other means - the ferry being one of them, whatever it was. Such news actually made sense to Lex, for he could not understand how anyone could survive the randomness of Arch-Heaven. It was even more devastating than Abaddon.
The mention of the fact that the value of this fort - a bastion of safety in the otherwise chaos prone landscape of Arch-Heaven - could vary either meant that there were a lot of such structures available, to the point that the inhabitants could pick and choose which ones they wanted to inhabit, or that there were very few people in Arch-Heaven. It could also be both, or neither. He would just have to continue listening to find out.
