Assign memorable traits

Give the NPC at least one specific, memorable trait and play that trait up. These traits become your touchstones for portraying them. Folks might not remember that the publican's daughter is named "Tegid," but they'll remember "the girl who runs everywhere."

Pick traits from the list of NPC Traits in the steading playbook, or make them up, or ask the players to do so. Write these traits down next to the NPC's name, along with their occupation or lot in life, plus any key relationships.

An NPC's traits might flow naturally from what's already established, but you can also pick a trait that contrasts with what you know or what you'd expect. Maybe the burly smith also knows all the gossip. Maybe the Fox's kind-hearted spouse harbors a hatred for the Hillfolk. Such contrasts make NPCs more compelling and memorable.

Based on what we know, I jot down:

ELIOS (he/him): farmer, humorless, ex-mercenary, Blodwen's uncle

I check the NPC Traits list, looking for an interesting contrast. My eye catches on "just got married." I think it's a bit fraught, and ask the PCs why. Vahid pops in with, "He married a younger woman, someone very talkative and bubbly. It's a weird match, but they seem happy enough. Well, she does. Elios is never happy."

I love it. I add "just married" to his write up, and make a note to figure out who his new wife is, too!
