Gillaine is a former member of the Open Wand party. A firm believer that Muggle technology is advancing at a fast rate. She thinks it is still inferior to Magical Might, but is not convinced that it will remain so. In her view it is only a matter of time before wizards are detected. The traditional mind manipulation spells don't work nearly as well in this internet capable age. She argues that if the wizards control the way the information is released, they will be in a better position to influence the results

She won the international dueling contest in Stockholm 5 years in a row, before retiring. She specialised in sudden brutal offenses overwhelming the opponents defences in multiple and varied ways.
