Nahiri

Nahiri, 'The Lithomancer' was one of The Three — a group of planeswalkers that included Sorin Markov and Ugin — that decided to rid the Multiverse of the terrible Eldrazi. Her identity was unveiled in the Commander 2014 supplemental set where she was a Planeswalker card. Being a lithomancer, she has special power over stones.

History

The Three decided to force the Eldrazi into physical form and trap them on a plane, sacrificing that plane for the well-being of the Multiverse. They searched for a plane with lush ecosystems and uniquely dynamic mana—a powerful lure for the Eldrazi's insatiable hunger. They found Zendikar. Sorin Markov lured the Eldrazi to the plane, directing their hunger to that unique mana, Ugin used his invisible breath to combat the Eldrazi and his colorless magic to bind them to the plane, and the Lithomancer constructed a massive network of stone hedrons, whose power would form the bars of a planewide prison, forever preventing the Eldrazi from leaving. Ugin arranged the hedrons to direct leylines of energy, which were not to be disrupted.

The planeswalkers concentrated the power of their imprisonment spell in a secret location deep inside Zendikar's mountains of Akoum: a subterranean chamber called the Eye of Ugin. To make sure that the imprisonment would not be broken, the three planeswalkers sealed the chamber with a mystical lock: the Eye of Ugin could only be reactivated by the presence of three planeswalker sparks—and the colorless, invisible breath of Ugin, the spirit dragon himself.

The planeswalkers' trap worked. Emrakul, Ulamog, and Kozilek manifested in physical form on Zendikar, became confined by the magic of the network of hedrons, and thanks to the magic of the imprisonment spell, sank into harmless dormancy. Their mission complete, the planeswalkers disbanded and left the plane.

6000 years later the Eldrazi broke free. In reaction, Sorin tried to reassemble The Three but was unable to find the Lithomancer. He found Ugin dead on Tarkir.

Identity

In the Uncharted Realms story "The Lithomancer" , the Lithomancer's identity is finally revealed to be Nahiri, and confirmed to be THE Lithomancer on Mark Rosewater's blog.

In the Uncharted Realms story "Sorin's Revelation" , a female character named Nahiri is mentioned in reference to Ugin, Sorin, and the Eldrazi, leading speculation that perhaps the Lithomancer is her. In addition, in the story "Dreams of the Damned", is revealed that Nahiri, skilled in binding magic, was the one who bound a hedron in Ob Nixilis. This theory seems to be confirmed with the release of Nahiri, the Lithomancer by Wizards of the Coast.
