Generate an NPC Backstory for a Tabletop Campaign

The players just asked the blacksmith a question you had not prepared for, and improvising a whole person on the spot is harder than it sounds. This generates a name, appearance, a distinctive mannerism, a three-sentence backstory, plot hooks, and a note on how they react to hostility, friendliness, or being ignored.
