Harlequins never use forged passports and driver's licenses. Instead, it's much easier to place a false name on a real identity card. An Harlequin like Thorn would use literally hundreds of false names during his life. It's important that he have one "true" name that can be used by family members and allies.

For Harlequins, this name is deliberately chosen by the user when he or she is between sixteen and twenty years old. Sometimes, the name is obviously symbolic, but often the meaning is known only to the individual. When a Harlequin child is growing up they are given an ordinary name so they can fit into the surrounding culture.
