Bríana Mullet
While Bríana didn't know what it was like to be looked down on for her "blood status", she had seen her dads be spat on, cursed at, and altogether abused for their choice in mate. So when Muggleborn witches and wizards started being attacked, she worked with Jess to help them. She fought for their rights. Due to her injuries, she didn't have as much pull with the media as she one did, but she had books on her side, and she had a shop that she was able to renovate to include hiding spaces for anyone on the run. She had a friend within the Department of Magical Transportation -- Floo Network -- rig it so the fireplace in Portable Magic only went between her shop and her fathers' house in Cork, and her floo was marked as "inactive" on all registries. She knew there was a battle at Hogwarts the night it happened because she heard the noises from her flat above her shop. She would have joined the fight, but as she went to join the fray, she heard the noises from Aberforth's pub and went in to help maintain order with the students there.
