The idea is a steam punk style world, but instead of cogs and steam, I imagine lasers, light and tubes. Power stems from an artificial liquid meant to be as close to angelic blood. When mixed with angelic blood(can be a single drop in an entire ten ton tank) a city could run for an entire week, and almost everyone has it in their house.
A specific company summons, captures and makes angels Bleed, possibly even ending some of them in the process.
(If you want) I imagine the main colour theme of the world to be a gray that feels like it is trying to be white but failing.
My inspiration was my brain doing some weird mix of the song "Encahnté" a specific line, steam punk and something minor attribute that I don't remember.
I'd like thoughts on this idea of a world element?
