Harry and Fleur are either engaged or married. After the war with Voldemort, they together left Britain and now live in France. Fleur works as an enforcer for the ICW, busting international trafficking rings and smuggler gangs or assisting various Ministries with trouble beyond their scope. Due to her actions and her dedication she came to be known as ‘Angel’, having saved countless people from a miserable fate.
Harry also joined the ICW and worked as a field agent for some time. However, it was quickly decided he was more suited for the role of a trainer. While his methods are unorthodox, they are highly effective. Among the trainees he is known as ‘Devil’, due to how brutal and gruelling his lessons are.
The leadership of the ICW quickly decided that while both are very effective at what they do, Harry and Fleur should not work together. The reason? Extensive collateral damage during their joint operations. However, should a sufficiently extraordinary threat to the magical and/or muggle world emerge, this rule is to be waived.
