This is a short guide to being an auror!
What are Aurors?
An Auror is a member of an elite unit of the Department of Magical Law Enforcement of the Ministry of Magic trained to capture Dark wizards and witches. Aurors are not necessarily the best of wizards, but they have a set of spells that others cannot use - look at the spell compendium. Aurors are loyal to the ministry and mainly fight against Dark Wizards, however they have also been called to attack half breeds and the order through their history.
At current time, Aurors have been depleted after the Battle of Hogwarts. However, they are coming back to their full strength. They are currently led by Gabrielle Delacour and the co-head Vincent Majere. Their main aim is to round up the remaining Death Eaters. However, they are also having conflicts with the Order of Pheonix.
Auror missions
Every so often, Gabrielle or Vincent will PM you with some auror missions. Auror missions are generally dueling ones, usually with Death Eaters, but not all the time. For example, currently the auror mission is the Horcrux hunt at Little Hangleton.
Auror in roleplaying
Aurors are not as highly respected as before, but people know that aurors are the more talented wizards and witches and are therefore intimidated by them.
