Eldrazi

The Eldrazi are an ancient race that once attempted to conquer the multiverse. Ages ago, they were locked away by three Planeswalkers on the world of Zendikar. Now, someone or something has weakened their prisons. The Planeswalker, Sorin Markov, one of the three that helped seal them away in the distant past, has returned to Zendikar hoping to reseal them. Nissa Revane, a young elf planeswalker who lives on Zendikar, aims to have them removed from Zendikar altogether, as she considers them FAR too dangerous to keep around.
