Warlock was once a man named edric black hawk but during the never side wars he became the High lord of the wraith lords and planned to bring chaos to the planet but was opposed by the Crowe family and eventually defeated him and banished the wraith to the never side until centuries later he formed a temporary alliance with the nekross to escape only to once again be stopped by the descendent of caractacus the one who banished him once before.
Long ago warlock was originally a cruel Wizard named Edric Blackhawk who from black hawk abbey made town people lives miserable with his magic but during the Neverside Wars, he formed an alliance with the wraith lords and became leader of the never side armies and gained the ability to use a wizard's own magic against them. During the last days of the wars, Warlock faced Caractacus Crowe and used his magic against him. But Caractacus's hobgoblin companion Randal Moon knowing if caractacus was defeated the world would be doomed and was able to stop this by chopping off Warlock's hand (which later became the Key of Bones).
In the end Warlock and the wraith lords were defeated and banished to the never side for eternity and cast the line of twilight to insure they'd never return he planned to leave the Neverside and unleash chaos in the world. Many years later after making a cloned Key of Bones, Lyzera queen of the nekross used it to contact Warlock from the Neverside and they made a beal for the wraith to take revenge on the wizards and the unenchanted when the stars aligned.
Warlock told Lyzera that she could have the creatures of the Never-side once she allowed him to enter the Dayside via The Doorway of Long Shadows. However Lyzera secretly planned that once Warlock came through the doorway, she and the other Nekross would extract his and the other Wraith Lords magic. After arriving at Blackhawk Abbey (where the doorway is) along with her husband Varg, Lyzera gave Warlock the cloned Key of Bones which turns back into his hand allowing him to step threw the door way. But when Lyzera and Varg attempt to make him surrender, Warlock aware of her plan used his magic to make Lyzera (also magical) and Varg fall to the ground. A wizard named Tom Clarke the direct descendent of caractacus along with help of an Unenchanted girl named Jazz James was able to force Warlock back through the doorway and Varg then destroyed it with his gun but Warlock say he will use the Chamber of Crowe to get through to the Dayside since Randal (the chamber's guardian) left it.
Warlock later gets through to the chamber and faces Tom's grandmother Ursula Crowe and Tom's father Michael who attempts to get rid of Warlock by throwing a Egg of Brimstone at him, but it has no effect and he knocks Michael to the ground. Warlock than plans to unleash the horde of wraith lords gathered on the never side on the world luckily Tom along with Jazz and Randal arrive having escaped the nekross ship and Tom having adsorbed all the magic from lyzera creates a tear and Warlock uses toms magic against him but he is able to fight back by using a combination of magic and science to blast warlock threw the tear sending him back to the never side saving the planet from utter chaos but warlock vowed to return and make the crowe family and all other wizards suffer.
