Gotcha, this post just so happened to pop in my feed (I re-installed lemmy yesterday after like a year). Didn't realise this was on a game, and the text is super hard to see, like the resolution is low.
To be specific, this is Dwarf Fortress. The game procedurally generates most of its content. Rusted metal is one of the potential options for divine metals, which is really good not bad like it sounds.
