Brothers
During the Civil War her brothers attempted to kill Wend with poison but since he doesn't like alcohol he didn't drink the wine. When they thought he was dead they attempted to place her under house arrest and Erwin von Arnim called out to Wend who used his Wind Blades to restrain their neck, hands, arms and legs. Wend told them not to move but they did anyway and lost their hands. They eventually committed suicide by drinking poisoned wine, along with their mother, given to them by their cousin Alfons who was to become the new head of the Phillip  household, allowing Therese to retire and pursue Wend.
