Today’s prompt being “Duel!”
Duels absolutely happen between the Gnomes of “Tock the Gnome” but are uncommon, held as a last resort in emotionally-charged conflicts. Most Gnomes tend to settle things logically and practically, and dueling is technically illegal. The Crown highly discourages them and in the noble/wealthy class, any dueling parties who are caught are always arrested. For the most part in the lower class areas, local law enforcement turns a blind eye to such matters – preferring to let such disputes resolve themselves instead of getting their own hands dirty, when they do (again, infrequently) occur.
I imagine these two are relatives, arguing over who’s going to have control over certain parts of their family’s situation, after an older relative has passed – all formal-meetings and lawyered-paperwork attempts at resolution having failed.
