Unsurprisingly, the remaining creatures of this plane have developed a lot strange abilities to have an edge in their daily struggle for survival. Innistrad is a dangerous place, which puts a lot of evolutionary pressure on its inhabitants.

The name of the next set in the block and a series of clues hidden on various cards in SOI also hint towards Emrakul.

Emrakul specializes in twisting all living beings, and her arrival on Innistrad would explain the madness and delirium various other inhabitants of Innistrad have recently been struck with. By now Sorin and Nahiri are estranged, and it looks like Nahiri might even have fallen under the influence of Emrakul, the last remaining Eldrazi titan. These three planeswalkers built the original Hedron network to trap the overwhelming Eldrazi in Zendikar thousands of years ago. The Zendikar storyline continues in Shadows over Innistrad, as the vampire Sorin is sent by Spirit Dragon Ugin to look for Nahiri. This balance has been put in jeopardy after Avacyn became inflicted with madness and a growing disgust for Humans. Innistrad had historically been stabilized by Sorin's creation of Archangel Avacyn, who was meant to keep the plane in a delicate balance by protecting the Humans from extinction.
