Biography
Ghaul was raised as a child to believe that he and his legion, the Red Legion, are the rightful beneficiaries of The Traveler's powers. He came to believe that The Traveler made a mistake in choosing Humanity and the Red Legion would have developed into much stronger and more powerful Guardians.

At some point, Ghaul, with advice from the Consul, launched a successful coup against the Cabal emperor, Calus, usurping his throne and exiling him.

Later, Ghaul attacked and destroyed the Guardians' City in an attempt to prove his legion's worthiness to The Traveler.

In his attempt to forcibly take Light from the Traveler, Ghaul was killed by a Guardian. While still infused with the Light, Ghaul resurrected himself into a cloud of light, expecting to finally win the Traveler's favor. Instead, the Traveler awoke, broke from its bonds, and released a pulse that permanently destroyed Ghaul.
