->''The war between Urza and Mishra is over. Brooding on the death of his brother at the hands of extraplanar forces, Urza drifts among the planes. But the end of the [[Literature/TheBrothersWar Brother's War]] has transformed him into something greater. Deep within his heart, a spark has been kindled to a flame that cannot be quenched. Urza has become a planeswalker.''

'''Planeswalker''' by Lynn Abbey is the second book in the Artifacts Cycle, corresponding to the black and white portions of the expansion ''Urza’s Saga''. In the aftermath of the Brothers’ War, Urza has become a planeswalker. Driven mad by his brothers’ fate and the godlike powers suddenly granted him, he becomes obsessed with finding and destroying those who have corrupted his brother: the Phyrexians. The book is mostly told from the point of view of Xantcha, a defective Phyrexian newt who accompanies Urza on his journey across the planes.

Urza’s [[StealthPun saga]] is continued in ''Literature/TimeStreams''.

!! Tropes include:

* AscendToAHigherPlaneOfExistence: Unusually, the novel actually starts off with this event.
* BigBad: In this book, Phyrexia takes center stage as Urza’s archenemy.
* CelestialParagonsAndArchangels: A native of Serra’s Realm at one point explains the angelic hierarchy to Xantcha.
* FluffyCloudHeaven: Serra’s Realm has shades of this.
* {{Foreshadowing}}: Urza’s musings on the possibility of traveling back in time to prevent Phyrexia from coming into existence. Read the [[Literature/TimeStreams next book]] to see how that turns out.
* GadgeteerGenius: Urza, once he sets his mind to actually working.
* HeroicSacrifice: [[spoiler:Xantcha and Ratepe save Urza from Gix.]]
* LateArrivalSpoiler: The Thran have become the Phyrexians.
* MindRape: Gix does this to Xantcha.
* NoBiologicalSex: Xantcha, who identifies as female after being {{MindRape}}d by Gix.
* ReallySevenHundredYearsOld: Urza being a planeswalker, he can look as young or old as he wants to. Xantcha physically resembles a thirteen year old boy, but is actually over three thousand years old.
* SpeakOfTheDevil: The Phyrexians have a strong taboo against speaking the name of their ruler Yawgmoth, referring to him as “The Ineffable”.
