Zendikar is a world of danger and adventure, deadly traps and priceless treasures. However, few remember that this world is also the prison of one of the deadliest threats in the Multiverse: the nightmarish Eldrazi. Nissa Revine, a Planeswalker and proud war elf born on Zendikar, witnessed what the nightmarish spawn of the Eldrazi are capable of. She still does not know that these monsters are just a pale shadow of the titans still slumbering in captivity. However, the mysterious Planeswalker Sorin Markov is familiar with the power of the Eldrazi titans firsthand. He was one of those who imprisoned these otherworldly monsters many thousands of years ago, and has now returned to Zendikar to make sure that they have not yet escaped. In search of the source of the Eldrazi's awakening, the two Planeswalkers embark on a dangerous journey across the world, not knowing... how their mission to save Zendikar will end.
