Steampunk world-setting sheet for a water city (free to use)

I found a free steampunk world-setting sheet on note, set in a decadent water city reminiscent of Venice. The author is 風嶺乃明. It is said that you may use and modify it as a basis for novels, manga, games, illustrations, TRPGs and more, for commercial or non-commercial purposes. However, redistributing the setting sheet itself as your own work, or reselling it, is prohibited.

At the root of this world is “artificial oil” (ocean oil). It is made by extracting carbon dioxide and hydrogen from the lagoon that surrounds the city, and the polymer made from it resists the rust of sea breezes, supporting the city's wealth and industry. I felt that technology tied to the environment makes the world more convincing.

Vehicles are named after celestial bodies too: the armored gunboat “Neptune” that guards the city gate, the armored train “Halley” that runs along the sea bridge linking the mainland and the city, and the aluminum amphibious steam car “Mercury” used by nobles. I think it is a good example that deciding on a single naming rule gives the whole world a sense of unity.

I also found it interesting that tools are graded by material, with the finest goods called “star tools”, so that rank shows up in the language itself.

Building a setting from scratch is hard, so it is a welcome effort that a shareable base for a world has been published.
