You will get your answer, somewhat, in chapter two. I will say this much though, you are very warm with your theory.
The ship is a normal naval warship out in the ocean. The setting of the story is in Azish (name of the planet) and you are in Voxis, capital city of Strize (country you live in). No intergalatic traveling sadly.
The technology level is high but only in regards to military development. Humanity has focused all their energy into trying to defeat the exilliums that the huge leaps in advancements were centred around that and doesn't really expand to other areas.
So there are flying cars, hoverboards, nanobots, AI assistants etc but they are very much for those in the military mostly. In the wastelander background they live very low tech lives and orphan it a mixed bag.
