#WordWeavers 30 Oct What tiny detail about your world or a character will probably never matter to the plot, but you created it anyway? Hard to know. I like layers. A throwaway mention of "Holy Lead" as something with an XX import classification (existential threat) in The Silk Mind turned into the first scene I wrote for The Source of Fire and the premise of a steam ship run on a Holy Lead Furnace (i.e nuclear reactor). I might re-use *anything* for a future plot arc.
