Blood has been spilled.
Battle lines have been drawn.
Time is getting short as Tolaria races to find the one who will wield the power of the Legacy. Deep in the inner circle, the dark lord Yawgmoth sends out an edict: Kill Urza Planeswalker.
From the bloodlines of the Benalish plains, a hero is born.
Urza has started the Bloodline Project to create a mortal heir to his Legacy. But as the project furthers his followers are divided, with some leaving the project believing it has gone too far, while others strive to go even further with their test projects.
And Yawgmoth has awakened inner circle member Croag to oversee the creation of Rath and the death of Urza Planeswalker.
