Personal History

 with the ability to move itself and others through Shadow.

Though Merlin was targeted for many years by an unknown antagonist, he was content to remain on the Shadow Earth. However, he became suspicious when he discovered his ex-girlfriend was murdered by a creature from Shadow, and his investigation was the catalyst for his choice to leave Earth. During the course of his travels through Shadow, he learned the identity of his nameless enemy, as well as that of his friends. With the rapid increase of his powers, the Pattern and the Logrus each attempted to persuade him to ally with Amber or the Courts of Chaos, respectively.

Merlin has a very different personality than his father and, oddly enough considering his upbringing, considers himself to be a "regular guy". He lacks both the ruthlessness and the crudity of Prince Corwin, and seems to be almost allergic to ambition, a rare trait considering his parentage.

Merlin has two half-brothers named Despil and Jurt, sons from Dara and Duke Sawall. Jurt, believing Merlin to be the favorite of their mother, tries several times to kill Merlin; however, he usually ends up leaving some part of himself behind.

Powers

Merlin's magical skills are quite varied, owing to his unusual background. Being of both Chaos and Amber, he is one of the few people to have traversed both the Pattern

. In addition, he later walked Corwin's Pattern to give it additional power in the fight between Order and Chaos.

As the son of the Chaosian Dara, Merlin was trained in spell-casting, but he frequently relies on the objects he carries with him. Frakir, a piece of rope enchanted during Merlin's walk through the Logrus, warns of danger and acts as a weapon. When Ghostwheel is completed, Merlin occasionally "wears" it in the form of a bracelet. Merlin eventually discovers a ring of great power called a spikard, and abandons Frakir after Frakir objects to the spikard. Merlin also obtains an unusual set of Trump that contains many locations and individuals absent in a normal deck.

Merlin's other abilities include shape-shifting (a usual talent of the Chaosians) and Trump creation. He also uses the Logrus emanation to reach into Shadow and retrieve various objects, as well as "Logrus sight" which enables him to see patterns of magic and dimensional anomalies. Though he was trained in swordsmanship and other forms of combat, his talents are not found in those areas and he rarely uses purely physical means to fight.

Ghostwheel

Ghostwheel is a trump- and pattern-based computer constructed by Merlin in a Shadow where Earth physics do not apply. By Merlin's description Ghostwheel's operations involve "a lot of theoretical crap involving space and time and some notions of some guys named Everett and Wheeler

". Ghostwheel speaks with Merlin's voice, occasionally causing confusion, and usually takes the appearance of a spinning circle of light. Ghostwheel usually addresses Merlin as "Dad."

After finishing construction, Merlin set Ghostwheel to work indexing Shadows in the same way that a search engine

A search engine is an information retrieval system designed to help find information stored on a computer system. The search results are usually presented in a list and are commonly called hits. Search engines help to minimize the time required to find information and the amount of information...

 indexes the internet. Similar to a search engine, Ghostwheel can find, track, and retrieve objects from Shadow; this includes the ability to move people and objects between Shadows. Ghostwheel operates by creating pseudo-Trumps for every mutation of Shadow and then searching them.

Merlin designed Ghostwheel as a tool to be used by Random, King of Amber, for keeping watch on Shadow for the protection of Amber. When introduced to Ghostwheel and its abilities, Random was immediately struck by the construct's potentially dangerous power and ordered Merlin to deactivate his creation. However, by this time Ghostwheel had attained sentience

 and resisted shutdown.

After regaining Ghostwheel's trust, Merlin came to rely heavily on his powerful creation, and Ghostwheel features as a major subcharacter throughout Merlin's saga. By the conclusion of the series, Ghostwheel had developed enough that his support of Merlin forced the Pattern and the Logrus to treat the pair as nominal equals rather than pawns.

At one point, Ghostwheel asks Merlin whether it is a god

Merlin also remarks that Ghostwheel is certainly capable of passing the Turing Test

Mythology

The name Merlin refers to Merlin, the character from Arthurian legends. Both were sorcerers who were imprisoned in a crystal cave, although the circumstances were somewhat different.
