The Jump-Off is what passes for a spaceport in Blackrock City. It is little more than a flattened area of compacted regolith on the outskirts of town.
It is also an area of total chaos. Inbound transport ships jockey with one another for free landing spaces as vessels hastily unload and load their cargo bays. Armed guards shepherd shipments of mining machinery, foodstuffs, and other consumables amid a crowd of debarked passengers and those looking to book passage of the rock, who mill about while trying to keep from getting squashed by passing vehicles or scorched by launching starships.
There is talk of cordoning off docking pits and charging for their use, but nobody has been able to enforce their ownership of the landing zone. This hasn’t stopped a few from trying.
