As a part of the Skyblivion concept art team, I worked on an early redesign of the Deadlands, originally from the game The Elder Scrolls IV : Oblivion from Bethesda Softworks.
It is the dimensional plane of Mehrunes Dagon, prince of domination and destruction. In the deadlands, the ocean is lava, it rains fire and even the flowers are trying to kill the player. It's a very inhospitable place, and every element would have to look dangerous.
Nothing here is guaranteed to be in Skyblivion at any point in time, as these are early research and not final concepts. Hope you enjoy!
