The Elder Scrolls IV: Shivering Isles Preview

In addition to their PS3 preview, Voodoo Extreme has taken a closer look at Bethesda's upcoming The Elder Scrolls IV: Shivering Isles expansion pack.
The expansion starts with your character hearing a rumor that a strange door has appeared on a small island in the Niben Bay near Bravil, and that it should be investigated. The island is small, and is topped by what can be described as a giant, mutated Easter Island-like head with three faces. Everything seems different: rocks, grass, plants, water, etc.. We find strange mushrooms growing ubiquitously, with names like Putrid Gigantea (putrid with mottling and some green slimy nodes on it), Worm's Head and something called a Mushroom Tree Sapling.
