Auberon was born in the year A.D. 550. He lived in the Teutoburg Forest in Lower Saxony. His First Death occurred when he was 35 years old, and he fell from a tree. He was found by the Immortal Odolff, who became his mentor. Auberon lived the standard life of an Immortal, changing his name, and fighting other Immortals when he needed to.
By the year 1986, he was known as Bob Parnel. He worked for Handlink Software in Paris, France, in the area of computer technical support. Auberon had many mortal friends, and hadn't used his sword for years. In 1995, he was on the way to the birthday party of a friend, when he felt the presence of another Immortal.
According to his Watcher, she hadn't seen Auberon pick up a sword since she was assigned to watch him. It is reasonable to assume that she is also employed by Handlink Software, since she kept forgetting that the guy in the next cubicle was Immortal. He enjoyed the quiet life, playing penny-ante poker, watching American horror movies, and eating chocolate.
His weapon of choice was a hand-and-a-half bastard sword. Eventually, Auberon got the last laugh, when Duncan MacLeod broke Auberon's sword in two in his final battle against Kalas, leaving him weaponless.
