Something a bit different than usual. I wanted to get a visualized reference of what Al'KuhXul's rifts look like for when he does dimensional travel and all that fun stuff. Also, will be used in an upcoming comic.
The rift has some unique properties of its own. It's plastered with eyes that can be used to see through before Al'KuhXul even walks through. And the tentacles can manipulate objects/people, as well as being the primary way of closing the rift. In essence, the rift will "squeeze" itself closed.
