Zendikar is a dangerous world of lethal risks where brave adventurers delve into ancient ruins in search of priceless rewards. The storyline features no Eldrazi but we see the ruin they have caused. From the perspective of its inhabitants, it is a hostile place that seems to be actively trying to kill the creatures that have the audacity to live there. The danger is unrelenting: precarious terrain, cunning predators, natural disasters on a massive scale, and the still continuing Roil — the unpredictable ripples of change that wash through the land — all present a constant challenge to survival. Nahiri has returned to Zendikar, and is willing to do anything to get rid of the Roil. Nissa has also returned home, but for reasons of her own.
