Iona Rivers
Iona was working at the Ministry during the war, as part of the Auror Office. Her father, Graham, was recruited into the Order by Kingsley Shacklebolt and eventually Iona was too, her skills at warding being employed to place defensive magic around the homes of the vulnerable. She also passed information secretly to the resistence and this eventually led to friends being caught, though Iona herself refused to stop. She fought in the Battle of Hogwarts alongside the other Aurors who made it, but was nearly killed by an unknown Death Eater who hexed her in the head. The resulting curse spread to her brain and it took months of physical therapy to recover to the point where she could return to the Ministry, although she never saw active Auror duty again.
