Curate, connect, and discover
I really want to write out a plot where one of the main character's only trait is that they sneeze really strongly. The way that this does not make a completely boring and forgettable character is: by some odd luck, their sneezes keep pushing the plot forward.
Sneeze, the sneeze pushes down a door they otherwise couldn't open.
Sneeze, the location of the main characters is revealed to an opposing party.
Sneeze, the nonhuman villain from another domain stops his evil monologue to ask "what the hell was that!?"
The possibilities are literally endless
