A hero is not only defined by blade, oath, or spellbook.
What makes a character memorable at the table is that small sliver of humanity — the habit they can’t break, the belief they won’t question, the secret they hope no one learns.
Some quirks are humorous.
Some are unsettling.
Some are the spark of an entire campaign.
Use these for NPCs, party members, or factions —
to reveal personality, history, or trouble waiting to happen.
