Lindonia is the wife of the Paladin Lucero of Trinsic.
When the Avatar met her at the docks in Ultima IX, she complained how the loss of the Chalice of Honor had devastated her husband, who these days spent his entire time moping around over this. She'd tried telling him that it didn't mean he'd lost his personal honor, but he didn't listen. Lindonia couldn't believe that the Avatar wanted to help with the situation without wanting something in return, letting slip how the people in the city had become greedy and unreliable.
After Lucero had given his life to regain his honor, she was found grieving at his grave.
