Recent HistoryEdit

Fifth EraEdit

Lady Cyrenna Plumm convinced King Damon Lannister to grant Joanna the position of handmaiden to Queen Danae Targaryen.

Joanna's snobbery toward the other handmaidens made her the Queen's least favorite of her ladies in waiting. After Meredyth Tyrell deliberately informed Queen Danae of Joanna's past relationship with Damon Lannister, the Plumm was sent to the Riverlands to marry Harlan Lannett.

Sixth Era Edit

Joanna and Harlan returned to Nunn's Deep when Harlan's father was stripped of his titles at King Damon's command. Joanna was pregnant at the start of the sixth era.

Seventh Era Edit

After the death of her daughter, Cynthea, Joanna began an affair with Damon Lannister through the exchange of letters carried by her brother, Edmyn Plumm.


"Joanna is well bred and well educated, but it doesn’t matter how fine a child’s septa is, you can still be born stupid, and no maester can fix that." - Lady Jeyne Lannister speaking to Queen Danae Targaryen

“I didn’t choose Joanna. I never would have chosen Joanna. She’s completely insufferable.” - Queen Danae Targaryen
